People saying they'd buy one online and actually doing so are two very different things-People do the same for every new gun that's released.
If it would sell in big numbers there would be multiple versions on the market from the big manufacturers, they do their research, they know their target audience.
Whenever a 'what gun do you want to be made' or similar thread comes along, very rarely do you see mentions of the Browning and that's because the majority of airsofters aren't interested in the older stuff. The more modern and up to date stuff is what sells and as a result what the big brands make most of.
If there was a real demand then someone would've tapped into that.
For years people were raving on about wanting an m&p, FNX, USP etc from TM, the Browning isn't something that had that same pull and demand. It's a shame because personally I quite like it but I would never expect someone like TM to bother producing it
