I wonder if COD:GHOSTS will beat this. From what I'm seeing, GTAV has a few advantages:
Non-yearly (or biyearly) release schedule for an extremely well-known franchise.
No outstanding publisher issues of note, especially gaffes related to gameplay "dumbing down"
A number of factors contributing to somewhat inflated review scores including normal reactions to AAA titles and the GTA series' tendency to hit the right buttons for reviews that doesn't necessarily reflect on gameplay
From my own observations, GTA is an entirely different market. Sure everybody knows about CoD but in reality, not a lot of the people I know will buy the new one (and that can be backed up by looked at BO2 preorders vs Ghosts) but almost everyone I've spoken to either has GTA, is buying GTA or hasn't got the means to play it.
