I don't blame Capcom for porting RE4 to PS2.
Their job is to pay their own bills and look after their own shareholders, the GameCube failed to get a large userbase and missing out on the profit of a PS2 version would've been stupid on their part and damaged the franchise.
The PS2 version sold 3.6 million copies, which is more than double the GCN version, what's Capcom supposed to do, just ignore the $30-$40 million in profit they likely made off the PS2 version just to make Nintendo happy? It's not their fault Mikami started making bizarre promises in public like he'd cut his head off if the game came to PS2 (lol).
To the victor go the spoils and the PS2 whupped the GCN. Same thing this cycle with 3DS over Vita and Monster Hunter. Fanboys need to get over themselves, that's just smart business.
RE6 seems to be selling great too, so I doubt Capcom is all that worried about it. Even though it's not as "good" of a game, Resident Evil 5 outsold Resident Evil 4.
Fact is, Resident Evil is a series that's always sold best on Sony platforms, while doing very well on the XBox of late.
