Sam's doesn't have the wireless guitar for 360 for GH3 though (at least not the batch I saw and everytime I see Sam's mentioned that is the case).
To answer my own question continuing semi-off-topic on Rock Band--the latest sticker dates seem to be early November and the date they admitted the issue was Nov. 20, according to a thread on the Rock Band forums.
So I doubt stores get likely-non-defective bundles before Christmas.
Looks like the selection of free games you get is decent from EA on replacements, but I just don't want to mess with a refurb. And there is no guarantee you get a free game AFAIK. They have to offer it to you.
[quote name='Wanderlai']I found a RockBand 360 today at Sams ($159) and Guitar Hero 3 for every system. I bought the 360 versions of RBSE and GH3. I'll be returning the BB one when it gets here. [/quote]
