Wasn't sure where to put this...
I found this tweet soft of interesting. Granted I'd like to see an article for context:

Also Ice Network has a nice Q&A with Pechalat/Bourzat regarding competing at Worlds:
Icenetwork: At the beginning and throughout the season, you stated clearly that you would not go to Saitama and would end your career right away after Sochi. What made you and Fabian change your minds?
Péchalat: That's right. We changed our mind because Igor told us that we were ready to go and that it would be a nice way for us to end our career with an additional world medal. (Péchalat and Bourzat won the bronze medal at the world championships in Nice in 2012.) The fact that these Championships are held in Japan has motivated us tremendously. We have always felt warmly supported by the Japanese audience. We have been many times to Japan to skate shows. We felt that skating in Saitama would be a great way for us to thank our Japanese skating fans and wish them goodbye -- at least on competitive ice.
