Well, Namco DMCA'd my livestream. I'll stream a whole bunch once the game is out, but I had like 50 people who were all super into the game so it was sort of a bummer for all involved. Oh well, no great loss.
Most consumables I've seen have been finite. Super annoying for things like Titanite that don't drop in later areas but you need to upgrade new weapons. EDIT: Found a new area that I missed earlier on, and Titanite is all over the goddamn place. I'm swimming in it now, so maybe the finite merchant inventory isn't a huge deal.
Lifegems have gotten very limited. There's a merchant that sells a whole bunch but they're expensive and not worth it to me.
I haven't tried dual wielding at all. I'm very much a big-ass-greatshield sort of player, so having no defenses scares me.
I believe I chose the Warrior (which I think was the one with high Strength/Dex and low everything else). Beyond that, it's similar to DS1 in that it doesn't really matter at all after the first couple hours. To my knowledge, none of the classes start with a Pyromancy Flame, so if you're a melee class there's no real benefit beyond some tiny stat differences.
Cool thanks for the answers.
