On the first thought: I don't see it,they would still have to contend with a growing community of people who mostly want to play homebrew and open source games.
On the second: Maybe, but that might be seen as a barrier to publishing a game made for fun that just happened to be good. "Eh, I'll just give it away, I was only doing it for fun anyway."
Or just eliminate the fee in its entirety and take a slice of the revenue (or marginally larger slice).
I don't see how lowering cost of entry could be anything but advantageous to console makers.
