It's difficult to have an opinion at this point.
Depending on different elements this could be both a next gen beast and a simple upgrade to the 360 (2-3X the power).
The CPU is 6 cores, ok but considering that frequency isn't going higher than 3.2GHZ (the limit is 4GHZ), it all relies on the advancements made on the single core.
2GB of Ram is decent if there is at least an other 1-2GB of VRAM, if they're going with unified + embedded VRAM it's rather poor.
The GPU, again, it depends on what kind of cores they're using, even PS Vita has a quad-core GPU.
So it's early to comment, but it would be nice if the CES rumor is true.
