I know they still had both bundles left after the Tampa show. I sat in the first row directly in front where they gave them out. They had many left and reboxed them after show was over.
I would think that if you already have an order, you'll likely it. If not you're likely hosed.
AMD didn't seem pleased with all the non-tech general people there picking up stuff. I got one set. My wife and I took it to the car, then went back in. However, there were MANY people leaving and said they were not returning to hear the rest of the seminar. I saw grandpas there that I'd bet never turned on a computer in their life, only there as warm bodies to get the stuff. The guy ahead of me in line was with his wife and they were getting 2 sets of both systems according to the docs they had. AMD even stated during the show that they thought 1/2 attendees were not true system people. The Microsoft guy asked how many gamers there were, and there were a lot according to the cheers. They were less than thrilled when a prize winner's employer was Best Buy. The large amount of Boo's from the crowd didn't help either. There were a lot of very young people that were obviously not system people based on age and atire. I am a Sr. System Admin/Programmer, supporting PC stuff, Unix, and Mainframe am not the type of person they wanted either.
They said over 1000 attended, more than expected evidently since there were not enough chairs.
