If MS switches to GDDR5 now, did Sony make a silly mistake?

I think it's funny how many people dismissed the idea of having 8GB RAM on a console. And now, bang, both next gen consoles have 8GB just like Epic, Crytek and DICE were asking for.

8GB of RAM is good, but the cheapest Sony could sell it for is about $450. If MS really goes with GDDR3, they could undercut the PS4's price by up to $100. 

 

a similar hardware with cheaper RAM but integrated kinect2 to undercut the ps4 by 100dollar????
