Again, pointless to compare this to Xplay.
This is one big bulky controller with integrated screen.
Xperia Play is essentialy phone and has very convenient desing when it comes to gamepad, you can "hide" it if you want.
And again, Sony didnt say "we wont be making Xperia Play 2"
The anwser was something along the lines "we currently are not making Xperia Play" which rather means they were not working on new model, not that they ditched the whole idea.
I already argued in one of the threads that Sony WILL make new Play. They have everything they need right now or under development like new, mature hardware/technology (reason #1 N-GAGE and N-GAGE2 failed), Software which is not all supported by one model (#2 why N-GAGE failed) and a position to get enough regonizion for their device.
Playstation Mobile is still under development so I guess we can start waiting for XP2 after they get PSM fully geared and proper hardware (for that time) ready. Give it year or two.
