@mike.s mentioned up here that BR30 will most likely be the next bulb shape. I haven’t seen them comment on Edison-style bulbs, but I’d love to see that too. 
I’ve got a couple decorative Edison bulbs in pendant fixtures.
I suspect Edison bulbs may be more challenging because they’re transparent. All the electronics would have to be hidden pretty close to the base. You can see that they had to add a black band at the bottom of the Philips Hue Edison bulb, for example. It also seems likely that you wouldn’t be able to change the color temperature with an Edison-style bulb. The Philips one doesn’t support that. I’m not sure what causes the color to shift in the regular Wyze bulbs, but in order to have that on an Edison bulb, the tech that facilitates it would need to fit inside the tiny faux-filament.
