I don't think they would refer to 2012-2013. Maybe a mention to The Witcher 3 as "a big commercial success" or "critically-acclaimed".
I don't think they will delay the release either. They have learnt throughout The Witcher 3 term for sure. Also, I bet they won't show a "vitamined" demo gameplay as some companies did (Horizon ZD, The Division...). Just following Rockstar's footsteps. They themselves gave an excuse to haters to begin the shitstorm against TW3 with E3 2014 demo. They can't afford that with CP2077.
