Ya, I've found Jetfire, Mirage, & Grimlock in the past two weeks.
I've yet to see hide nor hair of them at any retailer around me. Wal-Mart doesn't even have any space set aside for Classics on the pegs, and Target is packed to the gills with wave one of the Deluxe and Voyager classes. TRU is so pathetic it's not even funny, since not only have they not stocked any Classics in about a month (outside of the Megatron vs. Prime two pack), they also, as previously mentioned, jacked the price of the Deluxe class up to 12.99.

I did notice that Target is having a sale on Classics this week (I assume this is nationwide) with the Voyager assortment (Prime and Megatron) at 17.99, and the Deluxe assortment (SS, BB, Rodimus, and Astrotrain) at 8.99. They also had the 20th Anniversary Prime on sale for 62.99. Not a big discount on those, but a discount nonetheless.
I may be out of the loop, but what do we have to look forward to after the UM vs. SW pack, Cliffjumper, & Ramjet?
I think the only thing I've seen outside of those is the WM Exclusive Devastator box set. Boxed images of that just showed up on Ebay earlier this week according to one of the TF site (I can't remember which one), but I've yet to hear or see anything solid on when UM vs. SW will show up. I'm hoping to have found Mirage, Grimlock, and Jetfire by then, though.
