Nice catch. I am expecting a "hard bundle" for the first shipments and a new 24-70L would make a bunch of sense.
If a 24-70 f/2.8L replacement is announced next year, then it will probably initially be made available to 1D X buyers only, but I can't see it bundled with a 5D Mk.II replacement -it would be too expensive.
Canon needs a major announcement at CES. Its the biggest spotlight of the year and the one that attracts gobs of press.
CES is not the only big show next year, there's Photokina at the end of September; traditionally, this has been the more important show (compared to the old, pre-CES integrated PMA) for announcing higher-end cameras.
