Truth is, if what half what half you guys is saying (which, for the record is, "there isnt anything you couldnt do in 2E") is true, then you just proved that a new edition wasnt needed as its all Player/GM preference and you can add, omit or write any rule you want.
The same could be said of 2e - why bother making a second edition?
Saying that you can perform the same kinds of actions in 3 as you could 2 doesn't mean there haven't been changes. There quite obviously have. The question is whether those changes are improvements or not. Someone can climb a wall in 2e and 3e, but you roll different dice, have different options and have different outcomes. Which results in a better play experience? We won't know for sure until the game is released and the fanbase has a chance to try it out.
