Rockstar has shipped an additional 4 million copies of Grand Theft Auto V in the past six months. During Take-Two’s earnings call, the company provided updated numbers for 2013’s best selling title.

In October, we reported that 29 million units had been sold to customers in under two months. Comparing the new 33 million shipped data against the 29 million sold number is a bit of a mis-match, but we can easily deduce that things have slowed down.

Thankfully for Take-Two, Rockstar is planning to release something on new-gen systems this year. The company relies heavily on the GTA developer, with this year’s financials heavily buoyed by GTA V.
