I fail see how Ryu making it smash will do any of that you guys seem to think Ryu getting in will automatically pave the way for snake to get in he won't. Considering that Capcom is supporting Nintendo far more than Konami is at the moment Ryu getting into smash doesn't surprise me,and although street fighter series hasn't had many games on Nintendo consoles. It's quite convenient how you people forget that Ryu has appeared on Nintendo consoles through crossovers. Simply because Ryu gets in doesn't mean he is promoting Street Fighter V he could be used to promote Project X zone 2.
Oh, really, Capcom is REALLY supporting Nintendo! Indeed, I see the once Gamecube-exlusive Resident Evil game on my W...forget about it, it's everywhere else except Wii U. But we have Street Fighter V...nope, neighter it. At least we have that Mega Man 1-8 collection that are the VC ones for a little price...nope, just for 3DS MOUNTHS after the PS4/XONE/PC relase.
Really, the only things that Capcom is making for Nintendo are Ace Attorney (which doesn't sell on any other console) and Monster Hunter (which, being a game that need millions of players, is on the most sell console as for now: the 3DS. If that console was the Vita, they wouldn't put it on the 3DS. Besides, if they really wants to help Nintendo, they could always put MH on the Wii U, but they aren't).
Konami may have not been the best supporter for the Wii U, but it has been great for the 3DS (MGS3D, PES, Dr. Launtrec, Castelvania, Love Plus...), especially when it had problems to became a success. Besides this, Konami is now in bad waters. In this last 3 years they have released less than 10 games, and they are almost quitting the console gaming for mobile.
And Snake could be used for promote MGS3D, but Sakurai himself confirmed that Smash isn't about advertising Nintendo, it is about celebrating it and what it have done in gaming. And Konami was a huge part of its history during the NES, SNES and N64 ages. They deserve a rep (
way more than SEGA, who tried to kill Nintendo in the past with some slogan like "Genesis does what Nintendon't!").
