I got a peek at the shelf layout at my local Walmart and dman7529 is right, MTT's, Tie Fighters and Star Destroyers are the extent of the SW polybag selection. I got the UPC's and what I believe is Walmart's SKU for each in case anyone needs their WM to check the status:
8028 Mini Tie (44 pcs per box)-
30059 MTT (51 pcs per box)-
30056 Star Destroyer (38 pcs per box)-
A WM employee was able to get an arrival date for me using one of their handheld scanners and the UPC's/SKU's from the shelf layout. Also, big thanks to nyjpapi for letting everyone know about the find.
