I almost never buy downloadable for console, I like to have a disc and know if my console dies I have the game always. This is not too bad on PC as we have steam, however if I do not get a bonus for getting it from steam or who ever then Ill get a disc 90% of the time.
If console sales go down, they will not disappear as people have said the PC will die out for ages. Yet digital sales on steam are high and this proves there are loads of PC gamers out there. The console will just become a different platform and size down to the PC in sales.
I think soon, not sure when we will get 2 consoles. We have 3 currently and one of them well drop out as consoles become less popular.
I am primarily a PC gamer, and I think some console player will come to PC as they see the console get older. People who play games on console everyday are the new hard core gamers and will go to a hardcore platform (PC).
Casual gamers will play there I devices.
