According to a GameFAQ thread, an unknown E3 insider has listed the following games that will be announced as HD remakes. The poster states to take this with a grain of salt (as with all leaks these days), but his insider has a good track record thus far. Here is the whole list.

 
Kingdom Hearts HD Remix 2.5 (PS3)
Grand Theft Auto V (Xbox One, PS4, PC)
Call of Duty Modern Warfare Collection (PS4, Xbox One)
Crysis Remastered (PS4, Xbox One)
Metro Redux (PS4, Xbox One)
Batman Arkham Trilogy (PS4, Xbox One, PC)
Mass Effect Trilogy (PS4, Xbox One)
Resident Evil 4 Ultimate HD Edition (Xbox One, PS4)
Dragon Age (PS4, Xbox One)
Dead or Alive 5 Ultimate Plus (PS4, Xbox One)
Ultra Street Fighter IV (PS4)
The Last of Us Remastered (PS4)
God of War 3 Remastered (PS4)
Uncharted Collection Remastered (PS4)
Halo 2 Anniversary (Xbox One)
Gears of War Trilogy (Xbox One)
Super Mario Sunshine HD (Wii U)
The Legend of Zelda: Twilight Princess HD (Wii U)
Pokemon Omega Ruby/Alpha Sapphire (3DS)

Interesting to note that there are a TON of HD remakes slated for the upcoming year. However again, this list isn’t confirmed. If this is the case it leads myself to believe that most studios are taking their time and working on something huge for 2015. To me this mindset is refreshing. Instead of rushing to beat the competition, why not take your time and release a great game?
