Quoted from taylor34:

Only recent. It's what happens when a bubble forms in your market. Basically it starts as:

a) company is producing a product in a niche market. Sales are decent, nothing special.
b) interest in product starts an uptick. Company starts producing more
c) other people start noticing uptick. They start trying to produce their own products. Meanwhile, original company starts making their product fancier and with fake collectible appeal
d) prices continue to rise on everything, old and new products. Lots of denial that there's a bubble, prices will continue to rise for a long time still.
e) market becomes saturated with new products, old products, collectibles, etc. People get frustrated with all the new products, as they can't afford or collect them all. Collecting becomes less fun. People start giving up on collecting and selling off their collections.
f) market crashes
g) only company a) is left, demand is a Shadow of where it was at point a).

That's the way these things usually work. We are at point d). I'm sure there will be follow up posts to this saying we aren't in a bubble as well, further reinforcing point d). The only question is how long it will take for the market to move to stage e), it could be 6 months, a year, 5 years, but it's going to happen at some point. There isn't enough money in the hobby to support all of these ventures while also making old prices rise. The trigger will probably be one of these manufacturers taking in a ton of money and then folding before making a machine.
