I stopped in to my local AT&T store last night also and 4 of the 6 sales people had the main display all disassembled and boxes of stuff to reassemble a whole new display, so I looked around the rest of the store and there were no Windows phone on display any where so silly me I thought it had to be for today's 950 release, when I started snooping around the boxes it turned out to be all for the LG V10... And MS is holding off releasing the XL for AT&T's release of the 950??
first store i went to didnt even know or want to know - they did have the 640XL on display. When asked , i was told they werent big enough a store - but yet they have a 640XL?
second store i went to, nobody asked me what i wanted or why i was there, the 5 of them were playing with the samsung 18" tablet... but on the same table - that was presumably new, they did have a windows 10 display, which had a surface 3 (i think), the display dock and the 950 on display, but no pricing for the 950 - it was fully setup , ready to go - i played with it for a while, then left, without anyone still asking what i wanted...
