Around my part of Chicagoland it's been quite barren. The Targets only have Wave 1 Maries, Wave 2 Hans and DST's, a few Vaders and some of the Wave 2 Legends. From Feb to May, things were looking promising at one Target where the first 3 waves were easy to find (sans McQuarrie of course), but then they hit a brick wall and only had a couple 30AC figs on the pegs.
Of course that's nothing compared to the local Wal-Mart. They got one case of Wave 3 at some point, I know this because I found a lone Jawa once by the WWE figs. They also got a case of Wave 2 Legends, but beyond that they've not had any 30AC single carded figures as far as I can tell this year. Hell they still have the same 5 TSC Naboo Soldiers on the pegs that they did this time last year. The store has been good at stocking comic packs and Galactic Heroes, but basic figures not so much.
