Unreleased Heroes Release Dates

So I've been looking at the heroes which haven't been released yet in Dota 2 and was wondering when they will be released. Currently Meepo, Troll Warlord, Magnataur, Centuar Warchief and Medusa are most likely to be released real soon, but when are the classic OP heroes going to be released?

In my opinion, Valve are going to release the best heroes last (when the game leaves beta mode), but then again I could be wrong. Can't wait for the return of Terrorblade, Abbadon, Bristleback and Slark...

So who do you think will be released last? The one which everyone will be dying to see on the Dota 2 battlefield?

I think Soul Keeper and Abaddon will be last, since they are really stronk.

I can't wait for DotA 2 to be fully released and be free to play, can't wait to see all that new members on DOTAFire willing to learn the art of DotA :3

It will be awesome. The most beautiful game in the world.

Cover boys for when Dota 2 becomes a full game :)

I thought Dota was planning to be released this month. Unless they will r,ease the game and continue to add heroes. :3

Really? Hopefully this is true. Then Icefrog can start with developing new heroes as well, but not like LoL where a hero is released every week....

waiting for more answer....

man haven't played soul keeper in like 4 years lol, anything new with him?

yeah, hes still a total ***.

He's a great hero, if you know how to play him, you can counter him easily.

I think DoTA2 might be done by the end of this year....maybe sooner. And I am absolutely positive the last hero they will add is Tinker since he changes the meta so much with those damn mines. Although I didn't play the original DoTA, I wanna try Slark.
