I'm aware. The code is much larger (~20 MB uncompressed) and thus it's much harder to upload, so it'll be made available a bit after the actual release files. The 1.15 source can now be downloaded from the JK2SE webpage. I like JK2's engine. Many JK2 players really dislike the JKA engine... it just... feels wrong, somehow. Can't really explain it. If you're porting things over, wouldn't it make more sense to port both games to the Source engine? (It's based on Q3...)
