HEADS UP:
ODIN SPHERE (new) will be sold by Gamestop/EB Games for $20 starting June 2nd ("Gamedays Sale").
A full list of the games can be found in the stickied thread 'Daily Deals and Discounts' under 'Gamestop Gameday Sale' started by GrandAmChandler. There you will also find a link to a ten percent coupon for the games on sale or (if you subscribed to GameInformer) the coupon is on page 37 of the most recent GameInformer.
Certainly not a ten dollar deal, but $18 (with coupon) for a game that is sold at most places for $40 is a decent deal.
Like last year it seems that the stores got plenty of stock for this sale and they will be put on shelves not earlier than June 2nd.
NEWS:
After multiple delays, CHAOS WARS, a GS/EB Games exclusive ($40) seems to keep its street date (beginning of June). GS/EB Games online has it already listed in stock and ready to ship.
