The addition of voice acting is absolutely fantastic, but it seems like the number of frames of character animation has been kept exactly the same, despite the hi-res graphics. That's a little disappointing, given the limitless disk space available now. I wonder if it's a technical limitation as a result of the weird switchable classic/updated hybrid interface? Makes me wonder what the rationale behind that design choice was. If I wanted to play the older version, I'd play the older version. If I play the updated version, I'd rather be fully immersed in it, rather than 85% immersed.
Granted, this is all based on a video of a beta version. I hope the final release is more polished.
I do wish I had the hardware to run the brand-spankin' new Tales of Monkey Island, though...
