No we are not in version 2.0
We are currently unaware when the new version will be released. Due to several issues and the secret wish of the IH team to work with Blizzard the version 2.0 is still under development.
Two kind of rumors are spread:
1) The IH team is held at real life dungeons and fighting supernatural beings so the version 2.0 to be realistic and based at real life experiences... Sadly this approach has cost the life of some of the less important developers.
2) The IH team will release the new version with Diablo IV just to inflict damage to Blizzard. So the question it isn't when the new version of IH will come but when the Diablo IV will released...
(Diablo->Diablo II took 4 years
Diablo II->Diablo III took 12 years
Diablo III->Diablo IV will probably need 36 years (if we want to keep the analogy))
