My money is on MS.... partly because they have the cash to toss on a title that probably wont make huge immediate returns in terms of actual dollars, but would go a long way towards netting a lot of positive publicity and winning the "hearts" of more gamers. Partly because it might help them in JPN, especially in aforementioned terms of perception. They can afford to take the hit, and they need more niche yet quality titles to help seperate themselves from PS3.
I do not see how Ninty would have a need or desire to spend money on it, just does not seem like the type of project they would want to fund themselves.
Overall, it slightly sucks if its MS... because I do not want a 360. But if Shenmue 3 comes to 360.... I will buy a 360. Hopefully I am wrong, and it shows up on ps3 =)
