Well, it's not about whether the Wii is capable of running the software, obviously.
Obviously. It's about developers feeling the Wii is not worthy of the effort and therefore most of them don't even try.
On basically the only example of a big title being on all 3 systems at somewhere around the same time, Guitar Hero 3 (?), it sold best on the Wii, or atleast significantly outsold the PS3 version, and it probably would have cost less to put a team on porting it to the Wii with SD assets than it would to port it over to the PS3 and optimize it. ROI was obviously better on the Wii version than it was on the PS3/HD version so why can't that be used as an example of where the gaming audience is?
I believe TW10 sold best on the Wii too, so it's can't be that there aren't any gamers that wouldn't buy the Wii version over the HD version if they had the chance either.
So what is it about the Wii that makes developers/publishers so confused that they sign off of almost nothing but low budget crap or low profile gaming that they wouldn't even bother to advertise?
Some might say that they don't believe the audience it there. Well, how would they know? When have they released a game that would interest that audience, informed the world that it was being developed and then advertised so that we knew when it came out? To be honest, they haven't..... yet.
edit: Stratos, how can you consider MW[reflex] a blockbuster? When has a blockbuster movie ever gotten a quiet release under the blanket of it's sequels release? MW2 on the HD systems was a Blockbuster title as it got the blockbuster advertising and marketing that it needed. MW[reflex] got no such treatment.
