GTA V in Final Stages of Development?

YouTube user GTA5videos posted an interesting story recently. A user sent channel owner Drizla a Rockstar Social log-in, containing a ticket submitted to support. He suggested a new idea for the forthcoming game, with Rockstar replying "New ideas are difficult to implement as (GTAV) is in it's final stages of development". This could indicate more info, and the release date, is coming soon, especially with the news on last week's Kifflom tweets. Could I be right in predicting GTA V's 2013 release date? The majority of fans have called GTA5videos out on this. However, it coincides with Rockstar saying the test version of GTAV was already finished a few weeks ago. Could we be hearing more news soon? Seems likely. On the topic of Kifflom, two new tweets were sent out this week. "Epsilonism is an expensive religion. Only for those with the wisdom to afford it" and "Triple tithing makes a true form more true." On top of these two Tweets, the account has been replying to many similarly cryptic tweets from other Twitter users. While it is still unclear what this all means, no doubt it will make sense in the near future.
