Instead of asking which alt-coins are the best or which will survive, I figured I'd ask which are already for dead or on their way out and why? the closest I could find is this list, which is a little dated at this point:

An updated version (5-29-13) of the list in your link is available here: https://bitcointalk.org/index.php?topic=134179.0

Keep in mind that different people have different opinions of what is "dead". For example, I'd say that Chinacoin (CNC) could be added to the dead list (no dev support, network has little hashing power) as well as many others that appear in the new/candidate categories of the above link. Additionally, there are just so many coins being released lately (nearly all are failures, many are already dead) that it'd be hard to track and make a complete list of them all.
