I actually saw the 4K DCP of Ghostbusters last october or november for its 30th anniversary in that very same theater where I'll see T1 + T2 + Genisys next tuesday. I surely hope they won't just show the Blu-ray of T2. I'm pretty sure that a few months back, in another theater, they showed the Blu-ray of Forrest Gump. It was very disappointing. Even the subtitles looked like the way they are on Blu-ray. That's actually what convinced me that it was the Blu-ray they showed on the big screen. I would much prefer that they show T2 on 35 mm if it's not a brand new remastered DCP. In fact, now that you said that, I hope they made a mistake when they announced "numérique".
