I'm debating which flash would be the better choice when mated with my 1d Mark 4. If I'm not misraken the New 600 is rhe the newer vodies. I don't expect Canon to have a firmware update to work with the new flash. What do you guys think? Rhanks in advance!

Either is fine, power is the same except the 600 zooms to 200mm (that's why it has a bigger guide number). Both will be fully compatible. The 600 incorporates the new radio triggering, the 58- is optical (line of sight) only. If you plan to use the flash with a modifier (softbox, etc.) radio triggering is better (but can be done with 3rd party triggers for the 580).

You may want to investigate whether the 600ex is going to compromise your maximum sync speed on the Mk4, and whether HSS would be completely effective. If you're just getting one flash, save yourself a bundle and get a 580exII.
