This negative started ever since the Wii came out, specially with Wii versions of games. the called "crappy port" vicious cycle.
It started with PS2 ports, then PSP ports, and a ground up B-team development. The results are games that were really crappy and many Wii gamers that were excited to play these games ended up with the biggest dissapointments. as time went by, new games arrive that were letdowns for being the quick cash-in-port with nothing new to offer. Until the point of making many Wii owners angry and not interested in the game whatsoever, even if this time the developer is being serious after learning the lesson.
CoD: MFR might become a great game, but the stigma remains to many gamers (a two year game, no new exclusive features to compensate for the long time, releasing the same time as MW2 on the Hd systems). While many gamers can fogive and forget, there are others that do not want anything to do with the development company.
What many developers and publishers do not understand (or probably ignore) is that you MUST NOT piss off or let down a customer or a potential one, once you lose customers, is hard to get them back
