It really is crazy how things are exploding this year alone, looking at your examples Jeff. It seemed to me there was too much stuff before, but it is really expanding since the Disney takeover as well. I feel for those who really try to be "completists" these days, although I'm sure there are fewer of those anymore. I know even Steve Sansweet has said as much with Episode VII on the way, that it is practically impossible to truly "collect it all" anymore.
I pretty much just focus on the Hasbro stuff anymore, with the odd other collectible here or there, but I really hope we see a simplification of the Hasbro line at least when the movies come around. I know it is probably wishful thinking, because it is all about retail footspace these days, but I miss the days of "here are Star Wars action figures (one line), here are some beasts, and here are some vehicles". I guess, like the vintage days, POTF2, relaunch, or even POTJ.
