El T, they are coming. You've been wrong repeatedly before.
(as I do love to point out everytime one of these threads come up)
It takes time and effort to get a new product to market. I haven't seen Sig telling everybody that it would be out in two weeks every two weeks for the last year and a half. That was Robinson, and they even managed to get their gun into production. (and yes, they exist. I had one, wrote it up for SWAT, and sold it already)
Heck, I've been waiting for a Kel Tec PF9 for a magazine review since February. That's the nature of the beast. I'm waiting for one of the Oly bargain ARs for another article, and I'm going to have to wait a couple of months to get one.
Gun people can be incredibly impatient about new products. We announced our .308 Saiga magazines, and told everyone that it would take approximately two months. We were wrong and it actually took us four. (the first several hundred go in the mail this afternoon). So over the last couple of months I've had to listen to all sorts of anonymous internet posters making snide comments about vaporware. That can be kind of annoying when you've spent over 40 grand of your own money on a project, and some kid is giving you crap about how come they don't have their magazines yet.
Sig's a good company. And it is a nice slice of market share. It makes economic sense, they've done the beta work, they've felt out all of their dealers (I'm a Sig dealer), and their reps have been talking it up all over the place.
You postulated a couple of years ago that the ATF would not allow the XCR, PS90, or FS2000 to exist either. And if I recall correctly, those were pumas and unicorns too.
Sorry El T, love ya man, but I'm going to have to do this everytime you mention pumas or other imaginary creatures.
