Uh uh! I'll play along! 2 billion dollars is dumped in SCE's lap for whatever reason, and I think they would try to do something along these lines with them.
1) Acquire an extra development studio (or start a new one from scratch possibly). They would probably try to go for a studio is good at doing games that attract a wider audience, like Mario Kart or Just Dance. That's the most glaring ommission in Sony's lineup I can think of at least, they've got a few games that tries to that, but nothing is really working.
2) Invest some money in the Vita. Maybe by adding more functionality (through software) or doing bigger ad campaings (when it's released of course). Not to mention trying to get it out as fast as possible.
3) Invest in some third party exclusives maybe? Or just throw them at the PS4 R&D?
