More heroes on the way?
There you have it, straight from the Frog's mouth. While nothing is set in stone for now, it is safe to say that there will be quite a few heroes being introduced in the new map version. On screenshots posted on other forums you can see a Kodo and a Phoenix. But will it be the five or six, as mentioned by IceFrog?
Gosugamers will keep you updated with the development of the latest version of DotA.
