your argument centers on xbox having more and better exclusives.
ps4 has just as many AAA exlusives as xbox coming up. more actually unless xbox dates anything for Q1 in which ps4 already has bloodborne and the order 1886. better is subjective but i don't think either has a clear advantage. halo is big but SO and QB are untested new IP from developers that have never score a huge seller,. ever. tomb raider is only timed exclusive and uncharted 4 will be bigger.
and than there is are hunderds of indies launching either first or (console) exclusively on ps4.
i see nothing to change the current tide. i don't think you will be even close in your prediction. the ratio will probably be worse than the 2:1 WW lead ps4 currently enjoys.
