Actually, since there's no longer any magic schools I could do without any of the old specialist wizard classes. There's a lot of different power sources in 4E. It would be prudent to create new classes for new power sources that kill the old specialists and take their stuff.
E.g. I'd expect the psionic power source to eliminate the need for enchanters, beguilers and maybe even illusionists.
Since Necromancers are pretty iconic adversaries and BBEGs, I'd definitely want to have them available as monsters or even better monster templates but I don't see a pressing need for a pc class. If they're done as a PC class, they might use the Shadow power source, I guess.
I'm also indifferent to the name 'Necromancer', though it seems WotC is fond of retaining old class names even if they don't (or no longer) really fit what the class represents.
