Yeah I really can't wait either, especially when they say this will be their best game ever.
What I really enjoy with ME2 is that it gives depth while still being quite casual. The only downside to Dragon Age for me was all the stats building and that, but with ME I understood what I was doing, it was hard which is fun, it had a great story that really sucked me in, great visuals, everything was perfect (in my opinion) It looks like ME2 will be "just" a great leap forward (not to be confused with Mao Zedongs Great Leap Forward).
