Pretty sure Sony intends to do this.
High profile games released in this period have a greater chance of success than in Q4. Less competition, no need to worry about aggressive bundling, sales will be strong through the Summer drought and there is no threat of ''bargain bucket'' post holidays since not much is released in Sep/Oct.
It worked for TLOU and probably would have worked for Uncharted 3 too. In fact I guarantee Sony regretted not doing this which explains why Uncharted 3 was so heavily bundled.
Basically Q4 is overated. Any company invested in exclusives with half a brain (aka nobody from MS post 2010 era) would know this and stick by this. I'm not sure why Sony don't just spell it out though. Perhaps they don't want other companies following suite.
