What?! Never! Well, maybe not never, but not in the foreseeable future.
There is some
evolution: high-voltage 510 attys, 510s from other manufacturers with subtle differences, a "special" 510 atomizer* used in NHaler's new
Magnum ... MEGA
batteries, atomizers and cartridges (for the Titan brand) ... totally new battery for the eGO and Tornado ... and dozens of battery
mods with fittings for the 510 atomizer.
* I have no inside knowledge on this, but I speculate that it is a low-ohms atomizer (the opposite of the HV attys) in order to "simulate" 5V, i.e., yield 9 to 10 watts. [watts = volts (squared) / ohms]
But they are all variations on a theme: the massive vapor producing 510 atomizer and its reliable manual switch button battery. And I predict that the standard-sized 510 (even with its low-mAh battery) will remain for some time to come. Many vapers (especially new vapers) prefer a small e-cig.
I suspect that some suppliers are just giving up competing on that model in a glutted market, focusing on smaller niches. If for some reason you can't find a supplier from whom to buy a Joye510, don't hesitate to PM me ... although I might tease you a bit for not looking very hard.
[FYI: Don't be misled by my above Ode to a 510. I am a penstyle man; I don't get TH from the 510 (love it for my non-nicotine
vaping, however).]
