I think Guerilla Games might finally announce their new IP during the conference and it will be the "Killer App" for the PS4

I have high expectations if they can meet them I might get an Xbox One.

@spike6958: I got that from another forum because that is what they also seem to think.

Campaign

Dual-Campaign (the new Character and Master Chief)

More Harder

Multiplayer

Bring Back Halo 2 Clans

More Maps

3-Team Multiplayer (Red vs Blue vs Yellow) (But keep 2-Team Multiplayer as well)

Slower Gameplay style

More Strategy Required

Co-Op

Just get Rid of Co-Op

Halo 2014,Halo 2 Anniversary,and Halo 5 Guardians ? What do you think as I believe the Halo at Last years e3 and Halo 5 Guardians are separate games, and Halo 2 Anniversary is probably gonna be announced at the conference as well.
