It's selfish of me, but I hope that this is delayed until after the Holiday season. We're taking a family trip to the park for my mom's birthday this year, and she's been looking forward to the Subs, because she had such fond memories of them growing up.
But regardless of when this refurb is done, I hope its more than just some touching up, and more along the lines of major enhancements. The angler fish needs to be significantly enhanced, the jellyfish scene could use some tweaking, and the Bruce scene with the mines could be enhanced (the Subs need to shake more! )
And maybe the entire volcano scene can be re-worked. As it is, the scene looks incredibly fake and flat. I mean, at the very least, incorporate some of the dated, but effective rolling lava effect found in the Primeval World diorama.
And Imagineering should call the voice actor who did the Captain's narration and have him record some more lines that will make the Submarine Voyage more about a Submarine Voyage and less about Nemo carrying the weight of the attraction.
