I haven't had the poor resolution that other people have been talking about on the PS3 but I would have to imagine that it will not be like that in the retail version. I know EA has made some questionable calls in the past, but I just don't see them releasing a game that looks as bad as other guys have been saying.
And as far as penalties go, it is certainly a concern but it's hard to gauge what it will be like after some tweaking of the sliders. We only get one 5 minute period to play per game and if I recall correctly, the penalty sliders are far from maxed out.
I know I'm willing to take the risk and make the purchase but I can definitely see where you're coming from.
