Well, part of the pressure/expectation I, personally, put onto the DA franchise comes from the fact that Origins (although not precisely Baldur's Gate) was decently close to a traditional BioWare party-based, turn based RPG/Infinity style game in that couple of year period when there weren't many bigger budget RPGs at all. Of any description.
This year, in addition to some great RPG style Indies, including Magicka with its cleverly organic magic system, we've had Witcher 2, Diablo 3 (beta), Skyrim, Kingdoms of Amalur is on the way, Heroes VI, etc. Those are just the ones I've had time to play. Some of those games do one or more elements of the RPG brilliantly. Open world, choice consequence, whatever.
What the others don't do is ...
a) the party

that quirky BioWare story thing (not that the other big RPGs don't have good stories)
I had the opposite reaction to a lot of people about the DAII hype. When I heard all the "button=awesome" stuff and "no tactical camera, get in closer and engage with combat" thing, I expected a control system much closer to Witcher/Skyrim and was a depressed little old school gal.
But, I played DAII on nightmare, and micromanaged my party. I enjoyed the combat more than any other RPG this year, just because it still has the party. I engaged with combat and learned how it worked in a way that I didn't in Witcher 2, for example. In that game, I just wanted to try out different choices and consequences. (And avoid the dragon squishing mini games.)
It's a tricky one. But, for me, if there are other action RPGs out there, doing the single protagonist, choice/consequence, open world, isometric (diablo), interesting other stuff, then DAII not doing absolutely everything is cool. Hell, the "rough around the edges" elf townies really just focussed my attention on things like Isabela's speckly sunburned skin, and clever party banter moments as you walked around samey dungeons.
DAII didn't satisfy the explorer in me, but Skyrim did. DAII satisfied other things. I don't think the hype beforehand really accurately portrayed the game. But, I wasn't looking for the game to do everything, just the few key things I miss from the Infinity days (and I was pretty happy, in the end.) No game does everything, but if you engage with its strengths, it is a great game, nonetheless.
