I actually really enjoyed DAII. The enemy spawning and the recycled dungeons are kind of a bummer, but like most BioWare games, the characters are good, the dialog is well-written, and the story is plenty compelling to get you through. It does use the ME style of dialog choice instead of the way DA:O did it, but the spectrum of choices are generally well-represented and I never felt constrained by it. I think for the price they're asking, it's probably worth your time to check it out.
As for the save import into Inquisition, they're going to have some sort of web-based way of porting your choices forward. I'm not sure if that means you'll be able to upload your actual saves from the old games or if you'll just have to fill out a web form or something, but there will be a way of importing your choices, no matter what platform you end up playing Inquisition on.
