The white elephant in the room is that the majority of gamers aren't there to role-play; they're there to play the game, and the role-playing gets in the way of actually playing the game. Furthermore, there is a minority of gamers that actively hate role-playing; it's rare to see them speak up in a forum like this one, but you'll see them in the store and in MMORPG forums. When time is limited, and sessions infrequent, time spent yapping about stuff is time spent not running through encounters, gaining XP, upgrading gear or leveling- i.e. not playing the game. That 4.0 will be focusing far, far more on playing the game is a good thing; those that want RP don't need rules to do it and those that don't aren't forced to deal with it. (And, thanks to the online gaming support, can get their game on far more often than they used to; like that won't have an impact.)
