I have received Gigawatt from MightyApe.
Glad to have it, though the box arrived crushed due to the oversized shipping box they used.
I noticed Popcultcha has it for preorder. $59.99. Not ready til June 2021 though.
It got pushed to the week leading up to Christmas so I guess January is when it could arrive.
Just saw on FB, Toyworld Aspley has gigawatt in the shelf...
Swung by Zing today to check the release date for Gigawatt. Currently listing as the 21st of December. Unfortunately I was also advised that the allocation they received was half of what they were expecting. My pre-order did not make the cut. Take it with a grain of salt as this just came from shop staff rather than higher up the food chain, but given Hasbro's track record this year I can't say I'm surprised.
