Unless HR is heavily traded in/sold used due to low replay value or consumer confusion (thought they were buying another type of game), I really don't see overall sales being front loaded, specifically because it is a new IP.
I'm sure many will remember that the "new IP" reason/excuse is one of the most common ones given for why a game that had generated a fair amount of hype among gamers before release actually turns a luke warm public reception upon release.
Uncharted comes to mind and everyone knows how that story turned out. Infamous was another if I remember correctly.
