Coding isn't the be-all and end-all of a successful developer's skills. Many skills that are employed during development will also be exercised when engaged in other tasks (eg, analysing, designing, breathing etc.).
I don't mean to imply that architects shouldn't code. Far from it - they should as it's a very effective way of defining and maintaining an architecture (and fun too). I just wish people wouldn't get so hung up on thinking that coding is the only way to get satisfaction from a project. Someone who worries whether they'll have to "give up coding" probably hasn't enjoyed anything other than development and so is probably not ready to be considering anything else yet.
At the very least I would expect the amount and nature of development to change otherwise they're just evolving into a very expensive development resource!
