No Halo 2 cutscenes with current gen remastering, just the originals - confirmed in the RTX panel. :\
The Arbiter's CGI model doesn't look to monster-like, and Tartarus looks awesome... Well really, the CGI in general is incredible, but I'm no fan of Cortana's look, which they could have at LEAST used the animation model actress from Halo 4 with. Ditto Pearlman, who I'm pretty sure Bungie actually legally cleared the likeness of, as they had with Nathan Fillion and Tricia Helfer in ODST.
