I've seen the Tarkin wave twice, and both of these were within three days of each other at the same Wal-Mart. The first stocking was when I found my "Lazy Eye Tarkin" (which I passed along to a friend), and the second stocking on June 14th was when I got my replacement. Since then, I haven't seen any of those figures again.
The WM closest to me hasn't restocked basic action figures at all since late May/early June (and that was the 41-44 case), and with the exception of more cases of that same C1 assortment and a single case of the "first 12" C1 case from 04/02/05, Target hasn't stocked anything either.
I only just saw the Antilles figures for the first time yesterday, and it was a single case at a single Wal-Mart that was quite a drive from where I live. It had been nearly two months since I had found a new basic figure at retail, and to me, that is just ridiculous. I'll probably never see the Clone repaints because of the "OMG HOT VTHF RARE" Ebay crowd who can get to a store at 8 AM, and I'm sure those last two cases with the final 12 will be a really fun experience to find.
Hasbro needs to fix HTS.com and sell this stuff NOW. If stores aren't overflowing with Clone Pilots and Neimoidians and Wookiees, they're completely bare, and Hasbro isn't doing a thing to change either situation.
