Took a look at the Technodrome forums and found this bit of info posted på Brock on april 18th:
"Yes, the figures may be delayed. I won't know until I see the first sample, which should be soon (like in a week, or so). Based on that, and adjustments needed, we'll update everyone with what we think the ship dates are.
I did get samples of the Mousers the other day (we had sent that project to the factory before all the turtles). These are so fun! I'm making some adjustments to the neck articulation. It'll be something you won't be able to tell from photos, but will be able to tell when playin around with them. It's a good thing."
