i highly doubt that the initial lack of coop would seriously impact sales. highly doubt. the only people who know about that are the core gamers who make up a small percentage of total sales. also, it's not a dealbreaker.
if your logic was to be taken, then little big planet should also be downgraded because it lacks the online cooperative creation mode at launch.
the same would hold true for battlefield: bad company. that game also promised conquest mode at a later date but yet that game sold quite well.
