GTAV on track for 25 million sold in 2013?

CVG reports on Cowen & Company analyst Doug Creutz who estimates more than 15 million copies of Grand Theft Auto V having been sold with the game being on track for 25 million by the end of the year.

"Based on the $1B three-day figure Take-Two disclosed, we believe the game has already sold through at least 15MM units."

"For a game to sell 60% of its first year units in just three days would be abnormally high; we estimate that Call of Duty sells about 45-50% of its first year units in its first week at retail."

"However, for now we are assuming that GTA 5 sales will be extremely front-loaded due to high gamer anticipation, and will also have a shorter sales tail given the launch of next-gen consoles in November."

What do you think? Clearly sales of GTA V have been frontloaded, but is there really reason to think new consoles will disrupt the longtail this much for the rest of the year.
