It's possible that there will be some turbulence if we can't scale fast enough, but the Core devs have a plan that I think will probably alleviate problems in the short-term, and will almost certainly allow for massive scaling in the long-term. This plan includes an effective max block size increase to 2 MB in ~April. If any serious problems occur, it will be due to altcoins-in-disguise like XT and Classic trying to move Bitcoin development from something based on technical merit to something based on dictatorship or popularity.
I haven't watched this drama unfold in a while so its productive to see some discussion was occurring off chain.
It's sad to see a Core Dev part ways but Bitcoin moves forward, 2MB is achievable by nodes and balancing halving with transaction fees becoming the next incentive for miners is a part of Bitcoins experiment only time will tell what choices were correct in the end.

Wonder where the old timers go?
Various places as a means to filter out the noise but they are around just lurking
