Sounds good. 1.2TFlops as previously rumoured, plus indications of improvements in efficiency.
Both the PS4 and next Xbox will be powerful enough.

Not to be a jerk, but there's no indications of improved efficiency.
The ESRAM compensates for the DDR3 RAM's lack of bandwidth, but 32MB isn't enough to hold duplicated frame buffers with z-depth and alpha channel data. The 360 had the same problem, why one often saw games in sub HD, the solution is tiling, but it's complex for the developers to keep track of. To make tiling easier, there's added 4 move engines, which handles the tiles as ordinary page-files.
The thing is that Obis doesn't have any of these issues because the team/Sony went with GDDR5 RAM, no bandwidth issues or complex hardware architecture to compensate for.
Even worse is that ESRAM and move engines take op space on the die, which in the Orbis is used for the 16ROPS and 6CU's, meaning both machines use about the same amount of silicone, but the Orbis get a 50% performance increase.
MS has either made a grave design decision or they really need those extra 4GB of RAM for something special, which they think will improve the experience more than graphics can.
