Yeah, this has nothing to do with film vs. digital and has more to do with charging more for movie tickets.
However, who is "IHS"? How reliable is their prediction of what will happen in two months' time? Has anyone checked their numbers? This company claims to be "the leading global source of information and analysis" but I've never heard of them. I'm guessing they are ful of crap. They list very few sources for their info, make claims that are highly dependent on economic factors and speciaous at best - Avatar as the reason theaters are switching, as if it wasn't part of a concerted effort by a consortium of production companies that owned digital projection companies? C'mon, that's not analysis, or at least it's analysis that could have been performed by a third grader.
