Those screenshots are from 'Quake Wars' aren't they? If so, it's not the same engine, Quake Wars uses a modified Doom3 engine (ie. id tech4). So you cannot assume that the new engine will produce the same results. There wouldn't be any point in making a new enigne if it did.
The texture resolution does seem higher in the small preview that was shown of the tech5 engine. To me the potential big issue is that according to what Carmack says in one of the videos it takes up to 15 minutes to compile the mega texture, which is really too much for an edit, test, edit iteration loop.
