Hip Hop Gamer says Nintendo is in a position to acquire SEGA

[Soundwave]

To be honest, Sega would probably fit the bill for Sony a lot better. They kinda need a little more family appeal, even though they are trying with LittleBigPlanet and Wonderbook and what not.

Sonic could fill the void that's been missing since they lost Crash Bandicoot. Sega characters taking the lead in IP like Playstation All-Stars Battle and LBP Karting (replace that with Sonic All-Stars Transformed) would probably help those games sell a lot better. Yakuza and Virtua Fighter are natural fits on the Playstation. 

It would help the Vita out a lot to have an exclusive Sonic, PSO, Soccer Manager, Virtua Fighter, etc.

That said, not sure if Sony has exactly a ton of money lying around to spend these days, even though they have made some acquisitions in some other divisions, my guess is that was all that Hirai was given to work with, there's not a lot more money coming in.
