Avatar is still a year or a little less away, and who knows when ROL happens. I've been to AK twice since they offered it, and while I love the offerings (except *fart noise* Jungle Book) it's been pretty tame with crowds.
As much as ROL looks great, I don't think it would have made a difference with crowds. There is still a nighttime show, and while it may not be as grand as ROL's plans, the GP are more often than not clueless of any differences - especially since Jungle Book is an "It" thing now.
Only thing that seems to get a wait is Safari, and that's around 45-60 min wait. Disney may ride this out for the Summer, but put it back on the shelf until Avatar is ready to go.
