I think they were deciding if Wolverine should STAY with the team at the end or go off and continue being a loner (maybe paving an open end for the future "Wolverine" spin-off) I guess they kept with Wolverine being part of a family idea.
What's interesting to read in all of these reviews is that they think it will do amazing with general audiences but not the core fanbase. Probably exactly what Fox wanted in the first place.
Positive review of "X3" by Moriarty... some spoilers. Basically he says it's a good film on par with the first two films. http://www.aint-it-cool-news.com/display.cgi?id=23392
