Haven't seen this posted here but 343i released a bunch of information about Halo: CEA and a little bit about the Title Update. Everyone crying will be happy to know that the Title Update is going to try and add in the feel Halo 1 had along with the overpowered Pistol.
""More importantly," he added, "we're working on a title update for Reach and obviously for this that'll allow us to add some of the classic functionality and gameplay from the original multiplayer component [in Combat Evolved]. In some ways taken backwards, taken back to the sort of simpler... more elegant Halo experience."
That was a quote. He also added that some stuff might have to be cut if it doesn't fit well. But right now he said everything is going as planned.
Forge will be added to the CEA maps also.
"We're putting new Forge build pieces in the maps," O'Connor said. "A good example is Beaver Creek. You want to make that map a little bit bigger, so we've added some tunnels and stuff. In the classic mode it'll be blocked off, but you can take that out in Forge. With the Forge, all the stuff that works in Reach multiplayer with work in the multiplayer component of this."
So to me this looks like 343i is going to make CEA more than we thought it would have been.
I got all the information here from http://www.g4tv.com/thefeed/blog/post/715011/halo-combat-evolved-anniversary-edition-details-343s-frank-oconnor-talks/
There is also a lot more talk about CEA in there.
I'm not sure how to post links.
