Maybe. It's seems like they're being a bit half assed with their new releases. I actually just stopped collecting BT's. The last five (Sunstreaker, Windcharger, Prowl, Skids, and Tracks) are all Alt's.
From what I've heard at different TF forums they have six new molds and four repaints coming.
I'm pretty excited about Mirage but the rest I could do without.
