Nothing big was going to come of Diablo this Blizzcon anyway. They tried to say nothing big was happening and I hoped it was going to a remaster but that went to WC3. Sadly mobile games have a bad rep because of companies like EA. Without having played this I can't say what it's like but I understand why people are wary of mobile games from big companies with EA's track record completely mutilating IP's on mobile. I think that next year will be the big one and I would not be suprised if there was a D4 announcement then and even a possible remaster (Switch marketing for D3 and this would have died down). There are plenty of Diablo projects going on who knows what's going on behind closed doors.
