Assuming lockdown through to Easter and continued progress with vaccination, then we should be in a position by mid April where we have warmish weather, low case numbers and ~50% of the population vaccinated, so there's no reason the season wouldn't start on time.
We have a full season schedule organised from mid April to mid September.
However I would plan for the same rules as last summer - wide running lines, no teas or changing rooms and sanitiser in your pocket, and groups of 6 at the pub afterwards.
Scientifically speaking, the sanitation breaks were pointless last year, the virus doesn't really spread via fomites but by directly breathing in exhalations at a critical level that is hard to reach outside anyway unless someone is talking straight into your face from less than 2m for a prolonged period. Cricket is about as safe a group activity as is possible to imagine. Most transmission is within workplaces and households.
The scientific community knew this last summer, even if government guidance remains confused.
