It is difficult to say but the community is split into "8mb blocks or 1mb blocks" camps. I think that a solution will be found once the block increase can't be avoided anymore.
Too expand on this. The block limit could be reached in 1 hour. 2 hours. 3 days. 7 days. a month. 6 months. but its within the near future. for all we know the 2 fighting parties have a short term agreement that if it does hit the limit and the community hasnt decided yet then they both launch their ideas and the community picks real time. or a very short term solution is put in to give a little more time in deciding. we as the community are in the dark on what and when anything is going to be done
