Future for Singleplayer maps?

[tempest]

Sauer and Red Eclipse have quite extensive single-player maps and the facilities to make these fun and intense. Backporting anyone? *cough eihrul *cough

True, but there are few good maps that really make use of them. Eihrul even considered dropping SP from Sauerbraten.
As for RE, it's still fairly new, so we'll see what comes.
