It's interesting to see that duck.com is owned by google. This is what they call competition :)
The duckduckgo team should be smart enough to keep secret an upcoming name change/rebranding. See for example how comodo tried to register "let's encrypt" trademark: https://tech.slashdot.org/story/16/06/23/1946249/comodo-atte... .
It's not easy to beat google at it's own game. Good luck!
