Looks like FEDOR ANDREEV is now skating for Azerbaijan, according to the Men's Entries posted March 17th.

The entry is listed as "TBC" (to be confirmed), so I guess it depends on whether he will have official clearance to compete.
Too bad Yukari or Akiko couldn't skate for Azerbaijan or other country as well...
Would love to see the two at worlds this year.
