Here are some realistic ideas that I would love to happen and actually could happen, but still aren't very likely to happen (sadly):
Sony: From Software. Being incorporated into Sony's forum of first party developers would probably help them out on the tech side of things, which would help Demon's Souls overcome its one real issue - massive framerate dips. Under Sony they'd also be able to give Armored Core the love it deserves. I honestly feel that the Armored Core series just needs a bit more polish with every iteration, and that a little extra effort (in both polishing up performance and playtesting the game) could help the franchise break out of its tiny niche.
Nintendo: Mistwalker. I know this is a pretty new relationship for Nintendo, but I would love to see Mistwalker fully welcomed into the fold of Nintendo's first party efforts and given a dedicated development team to call their own. Sakaguchi's brains and Nintendo's brawn (and funding!) could lead to absolutely amazing things, especially if Miyamoto sticks his head in every now and then.
