Diablo 3???

I'd like to see a frist person shooter version of diablo.

Fuck no. Absolutely not. It would be horrible and you are a terrible person for thinking it sounds good.

Blizzard traditionally only releases 1 expansion per game, since Warcraft 2... I think they will make Diablo 3, it'll definitely be a while after WoW hits. I'd like them to expand the skill trees a little more.

Expand?
Why not merge, if they were to merge them all together as opposed to picking a character you would pick what you wanted to look like in the begining. From then on you would make a custom player, it would make it much easier to have a better variety, of course there would need to be more prerequisits so that you couldnt just be godly instantly, you would still have to follow a main course, just you could be with more than one character class. Just think a shapeshifting druid with barb skills or sorc skills, but they wont do it.
that would kick some ass thow.

yeah...pally with hammer, conc, geddon, burst of speed, teleport, cyclone armor, oak sage, BO, bone armor, evade and slow missles...
