In terms of new releases in Q4 why would they need more than UC4? There are so many exclusives coming out over the next few months that all those games can help to push holiday sales, especially with a variety of bundles. If Sony puts together 2 or 3 bundle options for holiday shoppers, one of them being Uncharted I don't see any need for anything more than Uncharted 4 to be launched at the end of the year. However as other's have pointed out there will be quite a few exclusives launched in the 2nd half of the year.
Add to that all the multiplats and there are more than enough games for people to be kept busy.
