As much as Shenmue III would be awesome, I highly doubt we'll see the same innovation put into it(if it were to ever exist). It would probably get thrown to some hack-job developers to whip something up, just to pull in some quick cash if they did make it.
I don't really like EA either, but that doesn't mean I don't like games like NBA Jam.
If you have a good rig you need to buy it on PC. I have both a console version and a PC version and the PC version looks and plays so much better.
If you don't have a high end PC then I'd say buy for whatever will run it best.
