Very interesting David... I caught Adam's post earlier as well. I wonder if this is why some Hasbro reps recently swung through all of my local Targets here and cleared out all the pegs. I haven't heard anything about an upcoming promotion yet, though I assume there certainly will be one to coincide with the CW line release. Do you think it'll be before the premiere of the CW cartoon "series" though? Can't even recall the date of that right now...
If I had to guess, I'd say it's likely that these are sitting in the back storerooms right now, 'til the big promotion (whenever that is), and anything that hits the market right now probably isn't supposed to yet - kinda similar to the whole midnight madness "do not put on shelves until ___" deal. Just my guess though. Guess we'll find out soon enough!

But based on what's currently available (and "in hand") on eBay from the CW line, I'd speculate that all that's going to be initially released if it happens soon will just the "army builder" sets, and possibly a couple ships. Plenty of the army builders on eBay, but not a single "in-hand" regular carded CW figure, so I don't anticipate those happening in the next month at least. The pre-sells on those state anywhere from end of June to August as far as availability dates...
