In podcast episode 255, E3 2016 Preview and Predictions, Will "boldly" predicted a total of 12 remake and remasters at the show. Here is our tracker, which I'll update leading up to and during E3 week.
Personally, I think Will's low balling here.
Confirmed remakes / remasters:
1) Final Fantasy XII: The Zodiac Age
2) The Elder Scrolls V: Skyrim Special Edition
3) Crash Bandicoot 1
4) Crash Bandicoot 2
5) Crash Bandicoot 3
Likely remake / remasters:
1) Final Fantasy VII Remake
Update 6/14/16: Added Crash Bandicoot 1, 2 & 3, announced during Sony's press conference and TES V: Skyrim Special Edition announced by Bethesda. Still no appearance from FF7.
