DotA 2 and DotA 3 Trademark Filled by Valve

Valve has made another step about their DotA game. After a while ago they applied for the DotA trademark, recently they also filled the trademark for DotA 2 and DotA 3.

This is a common thing for company who believe their game will have a sequel, such as Blizzard with Warcraft, Diablo and Starcraft series. Well, right now only time which can tell where this action will take us.

If you wanna see the details about the trademark application, check out on the links below:
- DotA 2
- DotA 3

So,will Valve followed Blizzard with their Starcraft trilogy? Or maybe they have another idea kept on their base? We'll see on the near future :)
