I don't know...edges seem far too smooth to be no AA. Interviews say the game runs on MT Framework "2.0" with RE5 running on "1.5". It seems unlikely that they would drop QAA with an upgrade of the engine.
Though even in the big Slug boss fight thing, I didn't see much jaggies and the framerate wasn't super smooth. Have they dropped the dynamic AA?
I dont notice any shift in sharpness like RE5 when the QAA kicks in with the LP2 demo; unless they adopted MSAA instead. For the 1st part of the demo, Im almost 100% sure that there isnt any anti aliasing. However, part 2 and 3 doesnt seems to be as rough as the first part. Environments looks smooth was probably due to the post processing and the glow effects that cover them up, but when you look at the character model, you can easily tell its very jaggy at any time. I just hope they are atleast have 2XMSAA lock and fix the dithering grass/transparencies effects in the final version. The demo is running very smooth already.
