Sure, but it will cost a few hundred dollars more. And many people might not want these just for games, but for media stuff, and they would find the $99 price a lot more attractive than $300-$400 for such tasks.
Not trying to denigrate the new device, just pointing out that comparisons are being made of a new device with a device which is near the end of its rather long refresh cycle. Of course that tends to favor the new device. I expect the xbox to jump ahead in performance by a significant amount after the refresh.
