I have not seen a definitive statement from EA saying that the form issue will be fixed via patch before/for the US release. Can you provide a link to something official from EA on that issue?
Aside from that, just looking at the UK forums, there seem to be many issues. Not the least of which is the freezing people are experiencing, some when trying to load their MM saves. Then there is the "night match" bug, where most matches are played at night (that one won't stop me from playing, but unrealistic nonetheless). Then there are the numerous issues people are having with transfers (not being able to make transfers, having their club budget go hugely negative after a season and then transfers not working, players being loaned out and then sold by the loaned-to club, newly signed players vanish after a game or two). Then there are the issues with the Assistant manager messing up your lineup before every match (again, probably won't keep me from playing, but still stupid). Anyway, I'm not going to go on, but you get my point (here's a list someone has compiled if you're interested, though it's not all MM issues:

I want it to be good, heck, at this point I'm just hoping for playable...but it took EA a while to patch 09 up to the point that it didn't freeze all the time on my 360, so at the least, I'm expecting the same for 10.
