Fair points in the most part
It'll be interesting to see how the conduit does, If it does what it promises then it could sell well and as a development platform Quantum3 might bring a means to get more developers building high end hardcore games.
Personally I think they should corral the original developers of the Gamecube ResEvil4 along with whoever implemented the Wii Edition and see if they can do for the Wii what they did for the Gamecube.
I do think though that with the naturally lower development cost of the Wii platform it doesn't take so many sales to have a 'hit' as with the big two.
