slides from digital possible?

As Grant already said, try to take a backup body with you. Though, personally, I intend to stick & travel with Nikon. I'm planning to take a digital Nikon SLR and a manual focus Nikon FM3n. The FM3n is great. It will take all latest lenses, and it doesn't need a battery. Fully manual. But WITH a battery, it provides semi-automatic (aperture priority) – the only camera with a hybrid shutter system.
But careful: if you plan to go that way (Nikon), make sure you get lenses that have an aperture ring. Nikon's "G" type lenses don't have an aperture ring any more, and if you put them on an old-school manual focus body, they'll only work at a fixed aperture.
