Yeah, I know this is a hot topic. But on the off chance that the people at ProVape have missed these threads, (which is actually pretty high, since they all ended up in the ProVari forum) I figured I would start one here. I'll list off the more commonly requested changes, just to start things off. For myself, I'm rather happy with my V1 ProVari.
Variable Wattage. Why people lust after VW, I'll never know (I've already heard all the reasons); but there are literally hundreds of people refusing to buy a ProVari because they expect the next version to have VW.
Higher Voltage/Wattage. They want at least 25 watt capability and the higher amp limit to handle it.
Flat Top Design. Some want a straight up flat top, others want a modular design that allows for both flat and tapered tops (and/or the ability to make a hybrid style mod).
Multiple Buttons. (I feel this would detract from the durability factor of the ProVari, as it introduces more points of possible failure).
Get rid of the Crop Circles. There may not be more people who dislike the grip grooves on the full size ProVari, but they are vocal in their dislike.
Provarinati Themed Custom End Caps. Not a version 3 upgrade per se, but something near and dear to my heart.
A three pack would be perfectly acceptable, containing the Eye of Ra Sigil, "Provarinati," & "Lumen Sees Totus."
More Color Options. Self explanatory. People want metallic, candy, etc.
Updated Display. Specifically, a Dot Matrix style military grade display, in keeping with the ProVari's reputation for durability.
Low Sub-oHm Capability. (In my opinion) the people asking for this feature ought to be given white dinner jackets with wrap around sleeves.
Ability to Upgrade V1 & V2 ProVari to V3. Self explanatory.
Get rid of the "--" in the Menu. It's unnecessary, and adds to the perceived clunkiness of the menu.
Reorder the Menu Functions. Basically, move the "On/Off" function to the end of the menu. It is probably the least used function on there.
Got more ideas? Go ahead and add them.
