Basic figures at my Wal-Mart just went back down to $4.77. Hopefully it is a sign of good things to come.
Wal-Mart just opened a brand new 24hr Super Center about 10minutes from my house. Not only did they have a great selection of #45-56 (only a few clone repaints though

), but they also had the $4.77 price that Ryan mentioned.
I think it's pretty safe that Star Wars will have a strong presence in the toy aisle through the Holiday season. Then, just like every post-movie year stuff will drop off from Jan-Mar only to pick up again in Spring. I think the 4" line will be safe through next summer at least, but depending on what Hasbro has planned for next year and how well it sells, anything can happen next fall...
