Why are they still using their old Xe2/Battlemage architecture rather than their new Xe3/Celestial? They already used it in their Panther Lake chipset.

Another comment here claims Celestial is cancelled. Has Intel indicated their intentions for the consumer dGPU space?

It looks like B70 was delayed 1-2 years for some reason.
