Did I?
j/k, yes, no exact date for the next release... uh, well, because I keep adding stuff to the dev's plate, ya know.
First it was just having diesels that had animated rockers, then adding a Chief role, then hey, may as well throw in a clutch, and supercharger, and well, hell, the e-motors should be playable... and realistically, so the player has to increase the load gradually or he will blow a fuse... fuse? yeah, better had an electrical closet... make that two... um... well, we need to disconnect the e-motor from the prop to charge the batteries, right? ... and why not add a "creep mode"? ... ok, you see where this going?
Trust me, when you see what the devs have done you'll leap across that line.
