The reason companies liked PS2 last generation was because it was the dominant console (in sales and appeal to most people). Every genre had good/best sellers. Xbox was the best console, but only hardcore gamers bought it. Gamecube was mostly first party software. PS2 is the most mainstream console and with sales of over 4-5 times more than the competition, there was no reason to not like ps2 even if it was a b***h to develop for. This generation, PS3 is the most powerful, but it's limited in appeal to mass market (mainly to price and blu-ray being unneeded for majority).
