I've seen this for the past couple of years, toys, well, as we know them, are definitely dying off.
You can see it with Hasbro and Mattel. The price hikes, the lack of availability, stores that offer these just don't have the selection they used to anymore. Of course there are a few exceptions and there are definitely different types of kids out there, but this hobby/action figure/toys are definitely going by the way side. The only real audience they have are collectors who are older, mostly adult who buy out of nostalgia.
You can see Hasbro, Mattel and other toy companies digging out a little niche for ADULT COLLECTIBLES now, trying to cater to them. They'll pay the higher prices, they'll want all that stuff and in the process, they push the younger audiences away.
What are Star Wars figures and GI Joes now? $10 to $12 bucks? I know those Bridge Direct Hobbit Figures are a HELL OF a lot. Legos too. Kids can't keep up with that, and electronic games, videos, computers, laptops, smart phones are much more appealing to them.
I've got two much younger brothers. One is 14, the other is 17. The 14 year old is really into GI JOE and Hasbro stuff. Clones, Stormtroopers etc. he reminds me of how I was with Kenner and stuff. But I can see that starting to fade. He's off and on again with it and has a pretty terrible attention span. One week he'll be on "MAN, I REALLY WANT A USS FLAGG", then he'll be getting pissed at Black Opps.
My 17 year old brother has always been into video games ever since Sega/Nintendo. Toys were never really his thing, especially when it came to the cool hand me down things I had from various lines. He can't appreciate toys at all, but he's older, so go figure.
