This has not been confirmed (or denied) by 343. So please take this with a huge grain of salt. The supposed insider has said they have played H5’s campaign and multiplayer.
If what they write is to be believe, then 343 is throwing everything but the kitchen sink into Halo 5.
Read on, potential spoilers. Again, THIS HAS NOT BEEN CONFIRMED. So do not take it as truth.

Please folks, do NOT tout this as fact. Even Frank O’Conner himself is a bit POed at this “leak”. Does that mean it’s real? Until/unless 343 states it is or isn’t, take it as something fan made and NOT to be taken seriously.
