Ga-rei zero, the anime adaption of the Ga-rei manga by Segawa Hajime is, like Kiddy Grade 2, to be animated by asread. According to Moonphase it is now scheduled to air this Autumn. Since they only have two completed series under their belt where they were the lead producers (Shuffle! and Minami-ke Okawari) they are unlikely to take on two series at once, making it look less and less likely that we'll see Kiddy Grade 2 air this year - which is frankly extremely disappointing given that is is well over a year since the pilot DVD went on sale.
Im not sure if you allready know but AIC Spirits is also working with them on the production of Ga-Rei -Zero-. IF i understand correctly asread is co-animation production on Ga-Rei -Zero-.
But it does seem that there is alot of the staff for KG2 is up in the air.
