I've just stumbled on this nice article from massively on the upcoming HoN 3.0 patch.

Personally I can't wait for the new models and textures at least. Been playing for 3 years so the bots aren't really a big thing for me, but still, this could get some more people back to HoN, that were previously " intimidated" by it's horrible horribly community and steep learning curve.
