That's truly amazing, but just in a slightly more than a month of development time, Kyrandia3 is playable until completion. Of course, there are lots of bugs, and the engine is not yet mature enough to be announced as supported, but the progress is enormous. Both LordHoto and athrxx added over 16,000 lines of code to kyra engine since 0.11.1.
There is no Kyra4 for them to continue their extraordinary work, as they seem to be on wave, but there are already certain plans from both. :)
So I suppose that pretty soon whole The Legend of Kyrandia series will be fully supported.
