we going to have to pay for diablo 3online?

Mike mentioned it in an Activision Blizzard investor meeting [paraphrased] "A player that buys Starcraft 2 at retail will have the ability to play on Battle.net with no additional fee."

I'll point out that this is a very carefully worded statement.

Q u o t e:

So you mean you have to subscribe to the online fee in order to find the high level weapons and use all of battle.nets features right?

No.

One pay-for idea that specifically relates to Diablo that I thought was kind of interesting was the chance to resurrect a fallen hardcore character.

I think this was mentioned by a fan, as far as I know we're not even thinking about these types of pay-for options yet. But, I think it's kind of interesting. I'm not sure if I like the idea or not, which is probably why I like thinking about it. There are some obvious pros and some obvious cons, but I'm not sure there's a clear cut answer as to whether it would work well or not.
