Yes, there are still people who make a living off flipping domains. Like any other industry it has evolved and continues to do so. With each new tld launched or a large sale, values are always changing.
As far as your 2 names that you have listed, I'm not so sure that they would attract any bids on Sedo but that doesn't mean that they don't have value. I have seen names on Sedo sell for a few thousand $ that I thought would never sell. Just be patient. You never know who might be interested in your names. I would recommend that you continue to add to your domain portfolio to increase your chances of a sale.
