I have several very similar domains that will expire in June - probably bought from the same list as yours. The odd thing is that they are getting people looking at them at Sedo - no offers, but movement. This makes me wonder if the "CCC.net price depression" is a Namepros thing and that elsewhere life goes on. After all, there was a lot of hype here a year ago about them and now it is renewal time.
I have renewed half of mine, trying to sell the rest for a small profit. I may cut prices further, drop them or just keep them. The profit potential on these is not as good IMHO as some other alternatives, but it is hard to let go.
