Sanjay, the first step will be to ask if there is consensus to use the process. Right now we have been collecting comments on the process then Magnus will send out a revised process and a consensus call to use that process. I'd expect that consensus call to and revised process to go out tomorrow at the earliest and possibly a bit later. That consensus call would last roughly 2 weeks. If there is consensus to use that process then the voting period would start and be at least a few weeks long but adjusted to be longer if it ran over a significant holiday.
