You raise a valid point. The G1 characters have certainly slowed down and yes, we don't need 47 Optimus Prime MPs. I'd much rather an obscure character like Skids than 3 Optimus Primes...
My pace of collecting has slowed, and really I'm only waiting for certain things I'm interested in (remaining cars & minibots, Astrotrain & Blitzwing - though any 1984-85 cartoon character I'll probably grab).
Yes I'll admit the accessories don't interest me either. That said, I still feel a $200 Hound with a bunch of random accessory crap (maybe it appeals more to the Japanese collector mindset? I don't know?) is a better deal than ... well almost every Beast Machines toy back in that era. Very few of which satisfied me for the price I paid. Hound is expensive but I am satisfied. It's a poseable G1 Hound that appeals to the nostalgic in me.
