A 390 Adventure makes no sense whatsoever. The engine is just not designed nor build for long distance trips. Sure, it'll probably be able to do 600 miles per day without much drama sitting at 70mph but the whole point of an Adventure bike is that it will do it comfortably and with ease. Not to mention the additional weight of all the Adventure "additions"
A 390 Adventure would definitely not be in direct competition to the "real" Adventure bikes, they'd be two completely different bikes aimed at completely different markets.
However, a 390 Enduro would make absolutely perfect sense. It'll still be a road legal dual purpose bike effectively so won't be anywhere near as race ready as KTM's proper MX/Enduro machines but it'll be a superb every day bike for green laning/commuting/having a bit of fun.
If the price was very similar to the Duke 390, then the Enduro 390 would make waves! It would compete with Honda CRF250L and Kawasaki KLX250, but would and should be a much better bike with lots more power on hand. GasGas EL CAMI 250 would also be a consideration but they don't seem to be pushing it in a big way.
Apart from the Honda/Kawasaki (which are a bit underpowered) there are no good dual purpose bikes out there (<600cc) which new riders may like especially to adhere to A2 licences. KTM should jump on the Enduro 390, and also the SMC 390 as they'd share almost all parts except wheels / suspension differences.
I would buy a 390 Enduro in a heartbeat and keep the Duke 390, but a 390 Adventure? ... definitely not! Would have to sell the Duke and buy the 690 Enduro R.
