Valve hints at Counter-Strike 2 with new trademarks and social media clues.

Valve has registered new trademarks for "CS2" and "Counter-Strike", sparking speculation about the upcoming release of a Source 2 beta for CS:GO. The trademarks relate to "entertainment services, namely, providing online video games." It is unclear whether CS2 stands for "Counter-Strike 2" or "Counter-Strike Source 2", and the "Counter-Strike" trademark could indicate a rebranding of CS:GO. These trademarks are some of the first concrete evidence from Valve that changes are coming to the game.
