As others have stated, and provided reference for it, it has not been deprecated...yet. However, i would imagine that a some point .IO will simply be turned over, sorry, sorry, sold over to an entity that manages TLDs like .pizza, .art, etc....Why? Because money; there's money to be made from .IO registrations....and if it stops being a CCTLD and becomnes a generic TLD...when there's more assurances that it will stay around, and hence more money to be made. I doubt it will disappear. ;-)
If yes, please give me a link, that would affect us big.
not yet, but it is a possibility after the UK promised to return the territories
