Projects have become bigger involving more artists and engineers. GTA 3 was released almost exactly 1 year after the PS2 release in Japan. Final Fantasy X hit Europe 2 years after the PS2's release in Japan. The PS3 hasn't even been on the market in NA and Japan for a full year, let alone Europe.
With regard to nobody complaining, there were actually many media articles which spelled the PS2's alledged doom.
