Not sure if this is sarcasm or not but from all accounts of people who played the Blizzcon demos say it's a solid game, as if they were playing D3 only on a phone. It is far from a crappy mobile game from a gameplay perspective. I'm sure it will have many of the crappy mobile monetization features, but as a game word is that it is not.
Also, if it were ready to ship, they wouldn't be mentioning testing phases in their quarterly reports.
