Sorry for my late response! But as others have stated, of course you will be able to run the new version on high settings. I can't go much into detail about the particular hardware requirements for certain settings, simply because we can't predict the final requirements yet (many features which will have an impact on performance aren't implemented yet). We have no definition for "Ultra" (or more precisely, we can't say yet which configuration can be considered "Ultra").
But to cut a long story short: You don't have to worry about the new version with this hardware
