no nostalgia disorder to go with it though. The first one was mostly the trailblazing 3D, but that trick won't work twice. Furthermore, viewers may have already gotten tired of '3D' by now. Speaking of which, due to the ticket being 1/3 more than 2D showings (somehow this is also the same between US and EU, which means it's not costs based), the profits may be suddenly higher, but the total number of tickets purchased may be lower. Which may be worth considering when comparing Boxoffice numbers between recent movies and their progenitors.
Btw, since this weekend is Christmas aka 'so boring I might as well kill myself' day(s), I wouldn't be surprised if TFA got a bumb up from that. Seriously, I hate Christmas just for how boring it is (and it being religious bullshit of course).
