Dota 6.68 Contains More Than 2 New Heroes?

IceFrog has just post another update on his blog. He is basically saying that he's still working hard on Dota 6.68. But what makes me interesting is these words: "There are quite a few new heroes in development". I'm pretty sure IceFrog won't use these words if there are only 2 new heroes on the next map. What do you think? Check his words by yourself:

I am still working hard on 6.68. We plan to release a preview video in the near future to showcase some of the new content. There are quite a few new heroes in development so we are taking extra time to make sure they are high quality. There will also be balance work done for the current content as well various other improvements and features.

If there is anything you'd like to see in the next patch, please let me know.

My guess is there will be 3 new heroes on the Dota 6.68. Some anonymous tipster also saying that the new heroes on the Dota 6.68 will be Icarus the Phoenix (Intelligence), Thrall the Far Seer (Agility) and Krakko the Fire Panda (Strenght). However, there's no confirmation yet about this, so let's keep that as a rumor. And another thing is, he will made a preview video on the near future about Dota 6.68. So stay tune!
