In theory the MassAve4 construction might include some improvements to Porter Square too; how much is up to the city, but faster buses are a priority they didn't address in original project and my impression is they want to revisit that. And so maybe that might involve partial reconstruction ala the rest of MassAve4, or not, we'll learn more this year probably.

Separately, if the experiment with concrete barriers goes well on Brattle St, hopefully those will get rolled out across the city.
