New FPS on the Way?

The following is an excerpt from IGN’s latest N-Query:

“…let’s just say we’re hearing rumblings of Wii-specific versions of at least one of the main FPS franchises out there. Oh, and when we say “Wii-specific” we don’t mean tacked on controls that claim to make it a new experience. We’re talking an immersive, competitive experience built from the ground up for Wii.”

All I can say is interesting..... We all know that Metroid is going to rock our world but am I clueless as to what title this could be. Will it play online? If I were to venture a guess, the only title that comes to mind is a Timesplitters game. What do you guys think?
