You're probably right on the whole only another GTA will outsell the last GTA, though it needs to be the only GTA and released at the end of the gen as for at least the next year and a half, people will be satisfied by GTA 5. The only thing which can actually outsell GTA 5 as of this moment though is COD if it reinvents itself enough this generation.
