Yes, they revised the hardware significantly at some point. Personally, I think they should have revised the model number at the same time.
The newer 48gii's added USB, a 4th battery, an extra 128k of memory and the equation library (actually I'm not certain that the last one was absent from the original 48gii).
Other differences with the 50g include a slide-off plastic cover instead of a pouch, a smaller display and a different color scheme (which I really like).

Yep, mine is the first-series model, then. 8^(
But hey, there would be no new model if there is no old one, right? (How much will these worth paying for in, say, 35 years from now? $$$$$... I feel like coburlin, somebody help me!!!! Doc?)
