The "Unleashed" Battle Packs are due sometime during the last quarter of this year - no idea on exactly when though. Not in the next month though, I doubt, or we would've probably seen some show up from some international eBayers by now.
As for the 7" line, yeah, the final wave has been delayed until sometime early next year. No idea why. But after that wave, it's totally up in the air as to when more may be made, since Hasbro said at SDCC that the 7" Unleashed line was going on an indefinite hiatus for awhile...
