Stupid ass washing machine...

I honestly don't really care about the multiplayer as much at this point, I'm worried there will be copious amounts of canon breaking; we can only pray that 343 an Microsoft GS will respect the canonical Bible and whatnot.
You can't break canon if there isn't any.
Halo 4 is, obviously, set after the events of Halo 3. No-body knows any of what happens yet. Karen Traviss is writing a series of novels set post-Halo 3 that, presumably, will tie-in nicely with Halo 4, 5 and 6.
As for the jetpack, as everybody has discussed, but as thousands of idiots will scream about... it's either part of his armour (take one looks at the back of Mark VI and you'll see it fits in, no problems) or, as his armour is different, he's wearing new armour.
