So after doing some more research, it does indeed look like the main culprit is GTA. Which is very interesting. I still reckon that it was already sold out on Amazon though. I think what happened is that people didn't realize it was sold out on Amazon until after the trailer.
This, along with the trailer jtself then triggered a rush on Pro units at other retailers. Best Buy is completely dry (as is Target).
The rush completely destroyed stock at Walmart and all of this, caused a massive rush at GameStop... where it is now also sold out after becoming the number one best seller (the Xbox 25th unit was number one for a while and at $1000 I cant wait to see how it ranks in $ sales)
Also, has anyonethought that a product like the Pro may be more vulnerable to rushes like this simple becauseit isnt stocked like the regular PS5?.
