The only way I see this happening is:
MS bring back the price of the Xbox One to $400
And when Microsoft go crazy in November and December for $300+game, Sony is able to respond with $300 + game too which I think will be possible since the PS4 will have 2 years in the market so a $100 price is quite likely.
But again, MS has to bring the price of the Xbox One back to $400 for this to be possible.
