Well, the game will be great, no doubt, but with all this demand for a Wii-make compilation of the first two, Retro, or perhaps a newer scrub studio could attempt on revamping the control and graphics of the first two games, while also working on a multi-player aspect.
That's an option I think Nintendo will consider, but I have to say, I think Retro is about ready to do something a bit new and different, and I don't exactly see HAL or EAD developing a rich first-person shooter multi-player experience happily. I imagine they'd want a Western developer, since the game is an FPS/FPA, but really, I don't think Nintendo likes to work with Western devs using their own IP.
