I don't know Bob...not sure if DMG is being given too much credit here. They bungled Looper before and now Transcendence, and the former did have a vaunted holiday release date in the weeklong October holidays and the latter its supposed major push with Depp's visit (but then again as you reported, that actually went South with media outlets and fans). Also read avid Marvel fans pissed with the "Chinese elements" inserted into IM3 way back when, which proved unnecessary (it wasn't a co-pro) and really clunky/clumsy (not sure THAT helped with Marvel's branding among movie fans).
I'm sure the one thing that Transcendence benefitted from was getting in, otherwise would have been a dicey proposition (same might be said re: Looper)...IM3 and the likes of TF4, I don't think any partners would have been necessary to get these in (not like they're stupid enough to shoot anything anti-Chinese in them to get banned), all signs point towards these movies being brought in anyway as part of the 34...like any Jurassic sequel, Spidey movie or a Jim Cameron directed movie...as long as nothing political in it (then again...Hunger Games movies are getting in, go figure, Panem = Beijing!)
It'll be interesting to see what DMG does with the Gerard Butler remake of "Point Break."
