I don't think you asking the nice people at Sinergy for a patch will make then do one. If one is planned, they'll be one. Think about it, the first one adressed some issues, but by no means all. They had to release a patch quite quickly, or the game will be considered not worth buying by the cashual gamer. All the problems couldnt be sorted in one patch.
As for gp5, I think we'll all buy it. It'll be the final gp game, therefore the best. After messing up gp4 somewhat, gp5 will have to be good. Also we know they're capable of good games, gp2, gp3 and 2000.
