I saw that a while back too, thats quite a worry, I don't look at buying a console every few years, if thats the case I won't buy more because I may as well just keep investing in my PC.
How do they get the idea of them not lasting as long though? The hardware is more powerful, the software is better and easier for devs to work with, I thought consoles basically controlled the market to some degree so from that I thought they'd be able to slow games down to continue working for years to come?
BF4 is much more stable on PS4 but as well as not looking as pretty as PC there are some quite serious fps drops on the market map (can't remember the map name but its Dragons Teeth DLC I think), like oh my lord, new console, but fps drops are huge.
