GSC Game World
Unknown, Presumably PC
|“|| Stalkers, while most of you are angry and upset (which we understand) please know that since December 2011 the entire Stalker team (myself included) was working without pay on Stalker 2 while new investors were scouted. That is our dedication. Sadly we could not gain legal rights to the franchise. We are still the same team working now at Vostok Games and on Survarium.|

S.T.A.L.K.E.R. 2' was a cancelled game in the S.T.A.L.K.E.R. series. It was a new chapter, which is why the name is S.T.A.L.K.E.R. 2. Due to problems in GSC however, the game's development have been indefinitely frozen.
S.T.A.L.K.E.R. 2 has been announced for a 2021 release by GSC Game World's Twitter account as of May 15th, 2018.
UPDATE [16/05/2018]: STALKER 2 has just been announced by Sergiy Grygorovych, owner of GSC Game World, developer behind Stalker. He made the announcement on his facebook page  and news has spread around various gaming sites. The official teaser site is https://www.stalker2.com/
Little is known of it; it is unknown if it will ever be released, but presumably it will be released on the PC and then to consoles later on[source/verification needed]. It will continue the story of the first three games as a new chapter and will still take place in the zone. Currently, it is known that the game will run with a new, unspecified game engine but will support DirectX 11. CryEngine 3 was in consideration.
Among the confirmed features as stated in the official interviews is that it will feature: new mutants, new areas, new uses for artifacts, and female stalkers. It is also confirmed that the main protagonist of the game will be Strelok and that the game's level layout will be a large-single-area game world to eliminate loading times. It has been confirmed that the game will be set in a triangle between CNPP-Pripyat-Chernobyl 2.
STALKER 2's development has officially been frozen, according to the Official STALKER FB page, due to GSC game world being dissolved. There were many rumors why: such as Sergei Grigorovich not being happy with the game's progress, a lack of investment into the game's development, internal conflicts inside GSC, or GSC running into severe financial problems. Although most likely, it is some combination of the following. 
While it is rumored that the game design companies bitComposer, who assisted in the marketing of Call of Pripyat, have bought all licenses to the STALKER franchise, this was debunked as false. There were also rumors that Bethesda Game Studios, known for their Elder Scrolls series, acquired the rights to the game, although this was also proven false. GSC still retains the license to the STALKER games (Contrary to the rumors that it has been sold off, listed here or otherwise.), as confirmed on their website.
GSC reopened in December 2014. However, there has been no mention regarding the STALKER series, and the company is currently working on other games. Therefore it is not known, but possible, that the development of STALKER 2 will be restarted in the near future. As of 2017, no news had ever heard for the announcing the game is developing, presumably that the project had been stuck in Development hell.
On Tuesday, May 15, 2018 GSC Game World released its S.T.A.L.K.E.R 2 website (https://www.stalker2.com/) and announced that it would be complete in 2021.
