One Piece 491 and 493
Funimation didn't include 492 on their site because that's the One Piece crossover with Toriko, which is under another contract, and which Funimation didn't license.
Yeah DeMarco said Funimation has been very late in getting them tapes for some reason.
But I don't think they're dubbing it literally a few weeks prior, because Sean Schemmel tweeted a few MONTHS ago that he was going to travel down to Texas just to record Goku Black in his entirety.
We can't until we know for sure what the April Fool's prank is. Can't very well plan for that right? I mean we can do it for the anime shows airing before midnight at least.
OR we can just make one the minute the prank airs.
