Speaking during an a conference call with investors, Take-Two Chief Executive Officer Ben Feder has explained that while the means of distribution has changed, its GTA development policy has not.

"Historically the franchise has been developed with initial multi-platform releases and then with incremental releases, in an array of ways. And I think we're following that here," said Feder.

He also hinted that more episodes could follow the release of The Ballad of Gay Tony, the second planned episode for GTA4 on Xbox 360.

"There are stories yet that still need to be told relating to GTA4. We're dealing with creative passion and talent and we're satisying and we hope always exceeding consumer expectation. It's one of the great things about what Rockstar does and is motivated to do."
