v1.5 is progressing. You can help by waiting patiently and checking http://dl.bukkit.org/downloads/craftbukkit/ when you want to know if there is an update.
Impossible question to answer. If we think we're close, but run into a huge problem after we gave an update, any status we provided just became a huge glaring lie. We would prefer to be absolutely truthful. The team is diligently working on an update. As soon as we can provide a build we will.
