I asked sideshow and they said they received a small batch to cover the orders that were placed in 2018 but the rest could be April so they are playing it safe by changing the date. Again. Though she said it could be sooner. I doubt it. She said they are suppose to send an email to all who have an order though so we'll see.
"Your order will be included in the future shipment, so far it's looking more like April than March :/
we did receive a shipment but it was a small one, and only covered the earliest preorders placed back in 2018, so we had to get those out first. The next one shouldn't be much longer than now, but we moved payments to April to play it safe."
