They do have more than 30 i think, but most of them are short lived, sony doesn't like to stick to one IP like nintendo does , its a miracle that they actually rebooted the Twisted Metal series to be honest. (and syphon filter if that rumor is true)

Sony version of Super Smash bros? Can we say murder? Sony has the most badass stable of characters I've ever seen.

They did. It was called Small Arms. Look it up...it was pathetic. Microsoft has no characters outside of Gears of war nd Chief. Actually Microsofts game shouldn't be a fighter it should be an open shooter.

Thats good for the sony fans that doesn't own a nintendo console, Super Smash Bros, is probably my favourite franchise, I still remember when I got the N64 game :)

That is, of course, if it is a good game.

where is my Jak and Daxter sequel then? =[

Nintendo has beaten their main franchises worse than a dead horse and you want to talk about Sony creating new IP's and not being able to stick to one? Imagine all of those IP's in one game. Thats just flipping insane. I loved when they put Cole, Sev, Helghast, Resistance characters all in Uncharted 2's multiplayer. Sony has a stellar stable of less kiddy and more mature characters. They still have the mature characters though.

Small arms isn't really like that, it doesn't use Microsoft characters , its just an indie game, using it's own characters, and its not pathetic its an okay game for a downloadable, also its not made by Microsoft, only published.

@Bolded

so how is that different from Nintendo?

I was kind of excited for something like this at first, but now that I've seen the possible characters I don't think I'd enjoy it that much

The mass majority of Microsofts games aren't purely microsoft  made. They are 90% published second and third party titles. Small Arms is a versus game meant to test Super Smash Bros. You cant do that if you dont have notable characters in the game. Thats the games selling point.
