I think it'll definitely be released in '08. Wii games don't take as long to develop, on average, and they seem to have a very reliable engine in place already. As long as they accept one of these offers soon, I'd put my money on a holiday release. Hopefully it's someone like Ubisoft, who knows how to properly market an awesome game (I can't blink without tripping over an RSV2 ad).
Also, I'm hoping this engine and those it inspires will lead to better quality/more multiplat games on Wii (obviously still not as visually stunning as their HD counterparts, but still great looking)
