Not yet, no - although once things slot into place and the game is at the standard I'm happy with, I suspect the Early Access launch will happen very shortly afterwards (like 6-8 weeks).
The points raised in the posts above explain the source of the delays. The initial idea for the strategic side game was much simpler in some areas, and when we realised that wasn't improving gameplay we made the decision to revert several mechanics back to the state they were in X1. I feel like this was definitely the correct decision for the project and I know a lot of people were very happy about it; after all a lot of people enjoyed Xenonauts specifically because it was the most complex and simulationist of the various X-Com esque games.
The problem though is that we can't just remake X1 and expect people to be happy with it. The Early Access build needs to demonstrate several interesting new systems right from the very start of the game so it's immediately clear that other changes to the formula ARE happening - i.e. having strategic operations or the signal uplinks on the Geoscape, having the modular armour system working with your starting soldiers, supporting greater equipment customisation on the aircraft, etc. I think people will be happy to give us the time we need to finish the project if they can see clear evidence that there are going to be interesting changes and new content, but I think we'll get a lot of negative Steam reviews if we don't.
So right now the main thing is to get those interesting new systems in the game. Once we've got a few of them working well we can name an Early Access date and then spend a couple of months frantically polishing the game in preparation for launch
