Exactly my thoughts. Even if it's slightly larger than the original Gen, it's still manageable and more than portable. I don't think it would end up bigger than my Thelema, really. Sadly, I don't see them doing it. The truth is people are buying pods and disposables mostly, and it seems companies have shifted their efforts mostly to easy profits, rather than catering to their better customers (better as in we'll spend more money more consistently). It's kinda sad how things are going. Pods I can see a use case for, but I despise disposables with all my being, and seeing them get favored over proper gear by manufacturers gets on my nerves.Agreed, given how they've shoehorned 2 18650's into the small gen200, it should be easy for them to do dual 21700 in the form factor of the original Gen casing.
I've had the Gen 200 apart when i tested it, and the way they've managed to pack everything into the mod, should make it a doddle with bigger cells.
