Actually, I like this update. I know that configurable buttons had been hinted at before but it's nice to see it become a reality. And I loved Sakurai's little comment at the end: "Wow. I hate to say it, but we really have thought of everything."
And I think everybody's going to have massive arguments over who the most deserving third party character would be and how they qualify to be deserving in the first place...
Personally, I think they need an eclectic mix from about 4 or 5 different developers all of which are very unique but thoroughly deserving. I know I'm not answering your question properly but for some reason, constant "Megaman" or "Bomberman" comments just bore me. Look at Snake guys... imagine it had been Sonic who had been announced as the first third-party, no one in a million years would guess that Snake would be one also.
So, I think that the most deserving ones are actually the ones that "yes, have huge fan followings" but would be completely unsuspected. Sure it'd be nice to play as Megaman for example, but I'd prefer -- say -- Ryu from Street Fighter as a playable Capcom character simply because he's deserving, would work well, AND would be a freakin' awesome surprise. Similar, sucks to Geno (again, like Megaman, I do still want him in, this is just hypothetical) I would much rather Cloud Strife or someone who's just completely "woah!" to appear.
So, Snake ; Sonic ; Ryu ; Cloud Strife
Hmm, who else... I've mentioned it before but I think Treasure is an unsung developer who deserves full attention. We've had Saki assist trophy, why not a Gunstar Hero playable character as creme de la creme. It's something that Sakurai knows that all true gamers would absolutely adore.
But the biggest pleasent surprise would have to be something like Banjo Kazooie, which I'm sure if it weren't for the whole "Microsoft" thing would be highly requested characters. Nintendo, you're in the big money at the moment... how many fans would be made happy to see that bird and a bear on a Nintendo console amongst Mario and peers for just one last time.
So, Snake ; Sonic ; Ryu ; Cloud Strife ; Gunstar Hero ; Banjo & Kazooie
The most deserving? All of them, because no matter what the people who claim that Smash Bros. should stay true to its origins, they would be **** well awesome, wonderful and BIG surprises.
Oh Banjo, it was if you were bred for Brawl, a unique double jump, a projectile, side attacks, and that unique pinache that just makes them the perfect character. Curse you, Gates! Curse you! I mean, It's one thing to buy up Rare, it's a whole diffrent ballgame to never make a Banjo Kazooie 3.
But I digress, yes I think that you're right. Some third Party characters should get in due to populairity, some should get in due to originality or uniqueness, but some characters will get in and currently (although I really
really want Banjo) the Bomberman and the Blue Bomber are pretty likely at this point. Personally, I think both are deserving. Megaman has all this high tech gadgetry, but Bomberman has this sort of classic aura about him, stemming from his classic game up to his later ones he's kept as original as, well, Mario. Tough choice, tough choice indeed. On one hand both could make interesting movesets with Bomberman's ballistic arsenel to Megaman's wide array of plasma (insert weapon here) and "flavors" (Fire, Ice, Electric...). Bomberman would slip right in with the zany cast of Brawl and has the anmation style to prove it, however Megaman has a very Samus feel to him without becoming a clone. Bomberman is with Hudson, which has had the responsibility of such big Nintendo franchises such as Mario Party, but thenagain, Megaman has been in about a bajillion GBA games that have litterally been flying off the shelves (Though he's never been n a console)
Then again, if you really want to do the unexpected get Lara Croft or Crash Bandicoot. Both iconic characters (in their day) and could probably get into Brawl without much heckling from Nintendo (Last I checked, Crash, Bang, Boom! for the DS was made by Nintendo's affiliates) and such totally impossible, yet incredible characters like Master Cheif would turn Brawl from a simple video game into a near literal fountain of gold. Ah, I really could see so many interesting characters getting in, in fact I think that it would be possibly the coolest thing in the universe if Brawl had every single main character from every major game in the world, but alas, that may never happen.
However, there is the matter of who I'd cast my vote foras the most likely third part canidate, and I, like the person before me, must say thatthe decision is just doo difficult to call, most characters I know are the best canidates imaginable. I can see either Megaman or Bomberman taking up that slot, but as to deciphering which I would prefer? Nigh impossible. Partially because I've only casually played both franchises and partially because they both seem to be the right guys for the job. Brawl is for the best of the best, and both of these gues are the best. Buat as far as who's better? Well, I can't really tell, it's mostly a matter of opinion, I aked the question mostly to see what the majorative reaction would be, but down to it, I simply cannot decide.
'Nuff said.
