There hasn't been much indication of them actually ceasing any of the celebration's offerings, yet. They'll probably return the park hours back to normal, so MK will close at 6PM again in the off-season, as it typically has in past, non-celebration years. As a result, it is likely that Spectromagic and Wishes will be presented just once or twice a week. However, that's, again, just standard things going back to standard-normal. I think we'll also see the end to the special celebration-specific dessert offerings, but in return we'll get new, non-celebration, special dessert offerings. The new things (Soarin', ME, etc.,) will probably continue as is for a while, though ME might gain a small charge.
