1. Grand Theft Auto VI Teaser Trailer
The Announcement: After the tremendous success of Grand Theft Auto V, the remastered edition and the recent PC release, Rockstar confirm that a sixth game is in development, complete with a first tease of what the next game will look like, hopefully set in Vice City (fingers crossed).
How Likely Is It?:-5/10. It's pretty much accepted that the sixth game is already being made, but remember that GTA V wasn't first announced until 3 and a half years after GTA IV came out, with a teaser trailer following the next week. Going by that pattern, a teaser releasing just 20 months after GTA V came out (that's less than half the length of the previous wait) doesn't just seem unlikely, it seems pretty much impossible. Yes, the next GTA game will likely release a little faster than GTA V due to the infrastructure now being in place for a current-gen entry into the series, but this would still seem hugely premature.
