polakis,
I still didn't read the PS doc, but AFAIR, they claimed to be cross-platform friendly now, so I have good hope it'll work as well.
Fed1,
1) yes, as exposed in a recent post, I'm going to switch to the PS once the Xbox one is done. I need to be done with it, and see if the game sells or not on consoles.
2) TE4 sales lowered by about 10% ; it's not surprising. I hope making the official release will help the sales (I might do it in June, before reworking the running animations).
3) One new tennis game seems almost dead on start, and the other one, we'll see how it goes, maybe it'll be good for TE, maybe it'll be bad...
