if you think they won't buy it I and most of the people I know won't be we also won't buy the PS4 if they do go down the same path.
I already spend more time playing games on my phone than I do on any of the consoles in the house (Wii 360 x 2 and 1 PS3) my son is most disapointed already that there is no Minecraft app for our lumias so switching to android will have him happy .
MS I think just got a little to greasy and controlling. Developers don't seem that enthusiastic either And they are not making it easy for Independant developers either.
If all else fails I am back off to playing RuneScape
