"... we have a very strong pipeline of yet-to-be announced titles in development. As a result, we continue to expect to achieve substantial revenue and earnings growth, including Non-GAAP net income in excess of $2.00 per share." (emphasis mine).
Why is this interesting? It seems unlikely T2 would be able to achieve such a figure without the release of a new Grand Theft Auto title. The release of Red Dead Redemption saw income rise to just over $1 per share, the last time it rose above $2 was during Grand Theft Auto IV's release. In the Q&A session following the release of this report, James Hardiman of Longbow Research asked Zelnick if the company could achieve this figure without a new GTA title. Strauss Zelnick, CEO of T2, answered the question making reference only to already announced titles such that are building on other franchises, namely BioShock and Borderlands, and completely avoided mentioning GTA.
So, while this is obviously no confirmation, it does give us somewhat of a pointer towards GTA V's release date (between April 2012 and March 2013). My personal guess? I think we could see R* moving back to the traditional October release, so October 2012. When do you think GTA V will be released? Let us know in the comments.
On a related note, the following video, courtesy of my friend Adriaan, is a humourous dramatisation of the question and it's answer. Enjoy.
