Yes. Although the new dead letter mechanism has nothing to do with it; 
that will allow you to reroute messages which get rejected, or expired 
from a *queue*.

If you want to save "unrouted" messages that are sent to an exchange, 
you can do that today (or indeed two years ago) - use the "alternate 
exchange" feature to route messages to another exchange that always has 
a queue bound to it.
