It hasn't been a secret that Kodak was ending their sponsorship of the Imagination Pavilion at Epcot, but both companies are now confirming it. In addition, Kodak will no longer sponsor Captain EO at Disneyland.
My guess is that the only reason they're still sponsoring Mickey's Philharmagic at the Magic Kingdom is because that agreement was signed separately and has yet to lapse.
Kodak still ponies up to be the official film company of the domestic parks, including Kodak Picture Spots. But if Fujifilm is still interested...
