Sega has updated their official Sonic website, "Sonic Central".
The update includes a 2 part interview with Yuji Naka(Click on "World of Sonic" at the top and then on the Yuji Naka graphic), which talks about Sonic as a character and mentions the possibility of an upcoming Sonic movie.
In addition, SEGA has added a "Sonic Web Developement Kit" to their website(click "Community" at the top, and then on "Fan sites"). This zip file contains a large amount of official Sonic Team art that can be used on fan webpages, so long as the SEGA copyright is mentioned. SEGA is also calling for the URL's of fan websites for a "Sonic Site of the Month" competition.
