I wouldn't bet on that weight increase coming soon, but that doesn't mean that Sport Pilot isn't a decent option if there are Light Sport Aircraft available in your area. They are capable airplanes, and with a SP license you can carry one passenger during daylight VFR conditions anywhere in the US and the Bahamas. PLUS, the training isn't wasted as you can count your SP training toward your Private license if you later decide to upgrade.
Many people start training for their Private ticket but never finish. If you do your training in an LSA, you can take a checkride part way through and at least lock in a SP license even if you never finish the Private.
I wouldn't bet on it either, but about the time I think it is a lost cause, I read an article saying the FAA is still working on it. Maybe one of these days! I am flying on BasicMed now, but it would be even nicer to just use my driver's license.
