The quest helper site, recommended uploading the relevant .LUA file for accumulated data.
They said they were working on updating the program, and anticipated a couple of weeks to do this.
Which puts that at, about a week into Cata.

The Blizzard quest thing, has auto progress tracking, if you set that option.
You get a number on the main map, which shows approximately where to be.
And an arrow on the mini-map, but that fades away when you get close.
So it is a lot less useful then Quest Helper was.

Carbonite had a bunch of other options in it.
But a quest guide is part of the addon.
Might be worth checking out.
