Default [Q] Waiting to upgrade

A noob question...

4.4.2 just arrived for nordic countries. Since I have a custom 4.3 ROM I have to flash the new 4.4.2 with ODIN, that much I understand.

My question is: WHEN there comes a custom ROM made from stock 4.4.2 will I be able to flash that from recovery or do I still have to flash the stock 4.4.2 first?

I want to know if I should be patient or just go for it... I really donīt want to go back to all Note 2 stuff if I know there will be a flashable deodexed, rooted, stock ROM in due time. My current setup is too Note 3-ish to just let go...

Best regards
