Check Point made some new additions in their release notes that better define the path to R77.10. It looks as though we are reaching a tipping point, in that certain versions on SPlat can be upgraded only if it is to Gaia. For example if you want to upgrade from R75.47 to R77.10, you can only do so if R77.10 will be on (or convert to) Gaia. Yet you can still download a SPlat version for R77.10. I think moving forward people need to be really careful as to what OS they are going to use, at it may limit your upgrade options.
