With a few days to spare before the August 2010 release date, LEGO S@H US has put up the Summer Star Wars wave. They are all in the “Classic” section despite most being “Clone Wars” sets, which may lead to some confusion.
A whole bunch of sets in this wave, so brace your wallets:

8089 Hoth Wampa Cave
$39.99, 297 Pieces
8093 Plo Koon’s Jedi Starfighter
$24.99, 175 Pieces
8095 General Grievous Starfighter
$49.99, 454 Pieces
8097 Slave 1

Free shipping on orders over $75 is still in effect, though the free Spaceman magnet does not seem to be.
EDIT: Use coupon code V001 (V-zero-zero-one) at checkout for the free Spaceman magnet.

Thanks to sadowsk1 and mr_joshua for the heads up!
