not sure if this has been posted but I just checked the current Toy catalogue from Target and on page 3 and 4 it has, The Lego Super Heroes Bat Cave listed for $399, UCS Hoth for $399 and the UCS Tie for $279.
I then quizzed the door girl about how long these sets listed above have been on sale at that particular store but she had no idea.
I then had a quick look through the shop in the Lego department but none were to be seen so they have either sold out or will be rolled out in the coming days/weeks.
