Matt said he's buying it the day it comes out and it will be his go to console, not sure why you are saying he's not a huge fan, he's just telling people to stop blowing things up to be bigger than they are.
I didn't take that last part as a shot at all, I know I'm not an expert at all I'm just going by what people who actually work on this stuff say who aren't in it for PR. We also have to remember MS will say things that make some things a bigger deal just for marketing reasons as does Sony so you have to temper expectations when it comes to what you hear from them both regarding their products.
The Destiny thing is kind of strange, I know I used Frostbite as an example of tech that I think seems to work better, then again they aren't really doing the same thing are they? Destiny is basically an MMO and is probably having to run other things in the background more than a straight up competitive MP shooter with destruction. I know that had nothing to do with what you said but I just threw that in there anyway lol.
