He is working on both games all the time.
"ADOM is undergoing active development and I'm planning some great stuff (or so I hope ;-) for the future. (...)Never again will there be an ovrly ambitious release schedule that leads to a delay of more than 18 months. The following parts will be worked on in the future (among thousands):
Monster inventories will be completed during the 1.x.y release series.
A rewritten manual for more clarity, better cross-references and an easier way to get into the game.
More quests, monsters, items, spells and secrets.
And then? Maybe a larger wilderness, definitely a couple of new races for the player (hill dwarves, ratlings, mist elves), item descriptions and a lot more. Stay tuned!"
"And 2010 is the JADE year… there definitely will be some kind of release early on(...)"
