well console upgrades are inevitable following the footsteps of the 360 and the ps3. Were the new modles were quicker one way or another. Personally I couldn't bare to play online with a fat 360 again after I got a slim, it was leaps and bounds faster on wifi even compared to a fat 360 using ethernet.
But the upgrades weren't really anything extra, it was always just a better design and performance. SO we will see when the 1st line of upgraded consoles come out. I really do think they will add more than just faster performance this time around but they will have to limit them selves as not to "kick the previous console buyers in the balls".
Basically nothing were a name like .1 is warranted. more like ps4 slim or fat for kicks because it's already pretty sleek.
