...Okay, I'm sorry, but WWW's lost me; WHY exactly does he have a problem with Banjo & Kazooie?
Because from where I'm standing, I see a duo that are:
1. Collectively two of the most requested characters ever (alongside the likes of K. Rool, Ridley, and Sora), and honestly since the days prior to Melee no less.
2. Have a history with Nintendo to the point that many (like myself) consider them Nintendo characters that simply are owned by a different company
and 3. Up until now haven't appeared on a Nintendo system proper since 2005's Banjo-Pilot.
With all that in mind, no freaking crap they were gonna hype this up, and the fans in turn ate it up, not to mention I feel like a lot of people beforehand felt that the Microsoft buyout of Rare severely hurt their chances, so to see this actually happen was something worthy to be proud of and build up.
Also, I don't get why you have such a problem with every DLC character having a trailer and a showcase; considering they didn't reveal all the fighters in both passes beforehand, they needed to market them somehow, particularly since there were likely people like me who bought both Passes before the entire roster was revealed. And again, I don't see the big deal regarding the showcases with Sakurai; he wanted to go into detail about each character, stage, and music, and considering that's what each pass was advertising in the first place, yeah, it makes sense to talk about this stuff.
So yeah, I don't get what your deal is about this stuff, dude.
