Saw a link to a 20s long promo at YouTube at Anime Banzai. Dunno how real it is. Supposedly comes in 2008. The title is "Hidamari Sketch x365": sounds like a name of an ITU-T protocol, honestly.

BTW, it takes a sadistic genius of web design to put a link into a ticker. Have fun aiming with your mouse. Sort of reminds me of those hideous flash ads, "punch the kangaroo and win".

UPDATE: TheBigN says it was announced at ANN.
