Yeah, while I've really been enjoying it, I can see why some have - or are thinking about - dropping out. I cut back to OT only, and have really enjoyed that aspect of the line from the beginning. Our daughter is really into them as well, so that helps keep things going too.
We just recently got the Slave 1 and Endor Attack sets. I really like the Slave 1 set, and look forward to more vehicles in the line in the future. The Endor Attack set sort of gives me buyer's remorse though. Literally the only thing "new" in the set is the Ewok with glider, everything else appears to just be a straight repack with no changes whatsoever. They could have at least repainted a couple ewoks or something. I will say, the new fold out dioramas in these things now are pretty nifty. Sort of wish I had the room to display them. I have kept them all basically, but don't really have the room to use them.
I think I'm caught up on this line for the time being. I still haven't gotten the Endor set with the Jedi Spirits (is that even released yet?), or the "Purchase of the Droids" set that was supposed to be a TRU exclusive but hasn't been mentioned since Toy Fair in February. Not sure if that one is still on the way or not.
