I agree. It would both be anti-climatic (both plot and relationship wise) and just plain not cool if they did that again, hopefully like you say it'll be something that'll bring them even closer together....and in a way, I think Sherlock coming back and all the emotional turmoil that will happen as a result could potentially, given time, bring them closer together as well. Still, I'm thinking that something will happen with John, which would probably involve Sherlock in some way as well, but the end of series 2 already resulted in something Sherlock character-based and to end the 3rd series again with someone Sherlock character-based would be...repetitive, so I'm thinking it'll be a primarily John incident...and knowing the writers, it'll probably something that breaks our hearts with both sadness and being deeply moved.
Long story short...series 3 cannot come fast enough!
