I highly doubt that we'll actually see Walt, and I really don't want to see him on the show. But the beginning of Operation Mongoose made it startlingly clear that the Walt referenced as an Author is indeed Walt Disney. The beginning flashback for the finale is set in LWM, December 1966, which is when Disney passed (December 15, 1966 to be precise). So while it was never explicitly stated, the implication of Walt as an Author is clear and obvious.
