Is the Sakura series causing the delays on the main SF book?

Just out of curiosity, is the reason that Street Fighter II is running very late yet again because of Udon’s resources concentrating on publishing Street Fighter Legends, or is it unrelated?

NO. Sakura is totally done by Omar Dogan, who does not work on the main book. The delay on SF II has a lot of reasons, but mainly due to Alvin’s work schedule conflicting with some client projects, as well as his travelling to various conventions, and other issues.
