I think for what is out around here right now, I'm just about caught up. I picked up the Dengar/Fenn Shysa comic pack yesterday at TRU, and if I can find the Leia/Dala pack from that wave I think I'm caught up with those. Otherwise, most of the other stuff hasn't hit around here yet. No sign of TLC Wave 3, Clone Wars Wave 2, or anything else newish. I haven't been hitting the stores quite as much lately since I'm not quite as jazzed about TLC Wave 3 (mainly want the clone and the Build-a-Droid), but things seem pretty full with the first waves and Legends at most of the stores around here. I still haven't picked up the AT-TE either, but I'm not sure that I'm going to be able to at this point.
Its funny how the collecting game has changed so much. The first line I really collected most of was the POTJ line, and I can remember being caught up for weeks or even months since the release schedule was so much lighter then. These days if you get caught up, its lucky if you can stay that way for a week before more stuff starts hitting. Not that more stuff is a bad thing at all, but it does make it difficult to catch your breath (especially in the 2nd halves of the year the last couple years).
