Interested in the progress of Ubuntu 10.04?

Here's a good place to follow what's happening.

It looks like the Lucid Lynx repositories are already open - just in case you were feeling slightly suicidal.

However, at this point there is usually a small flood of updates backed up from Karmic freeze, and then a steady stream of new updates as development progresses. New features generally won't appear until later in the development cycle and things usually go a bit quiet while UDS takes place. Most of the devs are discussing and planning, not coding at this time.

Karmic Koala is that good that I am happy to wait until later before taking the plunge to Lucid Lynx.

But for now - watching others with less impulse control is a good substitute. And you get to see when stuff breaks.
