Though I'd point out the obvious irony of commenting this
on an Avatar forum (

) it is of course true that for a long time and in a good way, the community has been what has truly bound us together, rather than the actual film itself.
I wouldn't use the term "moved on" - it implies nothing was gained - but rather it feels that for many, Avatar has moved from being a hugely important, active part of our lives, to something that's shifted into the background but still very treasured. I can't speak for everyone, of course, but this is a common and very natural cycle of any passion or life-changing experience
Nothing wrong with that, but this also doesn't mean we can't feel excited about a new, potentially also amazing experience!
It's easy to feel "Oh, Avatar's not as important anymore", but prominence does not necessarily relate to importance - it can exist as an amazing experience of the past and still be extremely important
