There has been a lot of rumours going around lately regarding Red Dead Redemption 2, naturally because the game is surrounded in mystery. We literally know nothing about it, and when comparing it to GTAV’s insane launch with billboards and buildings being plastered with giant posters, there is a definite correlation problem.
UK games retailer Gamesgeek has posted a listing of Red Dead Redemption 2, and according to that listing, the game will be out on October 20, which is similar to the date another store based in the UK posted but as October 2.
GTA V originally released in September 2013, so I guess one could predict the launch to be in the last quarter of 2017.
