Out2gtcha - I'll explain egain. It was our idea to release the P-6E (about year ago). Soon after Kitty Hawk contacted us saying they planned to release it as IP kit. At the same time we informed them about our T-6 planned release. So finally we shared aircraft between us - they took the T-6 (plastic) and we will release the P-6E (resin) as we wanted at the very beginning. I hope it's clear now
And yes - the Stearman and Demon are pretty advanced in progress so are planned to appear just before the P-6E.
