I've just emailed Vivid Toys, the manufacturers of the new Thunderbirds Are Go! toys being released this year. I have asked them to release a Zero-X toy! A long shot I know but if enough of us email then who knows! The idea just needs some "lifting bodies" to get it off the ground! ha ha.
So get scribbling guys and email Vivid here. For ideas, here's the one I sent [some personal stuff - email, phone - removed for posting here]:
VIVID'S INITIAL RESPONSE
Thank you for contacting Consumer Services.
Unfortunately we currently do not have any plans to release a Zero X toy as a part of this range, however we will be hopefully expanding the range in future and have passed your comments onto our development team for their future consideration.
If you have any additional enquiries, please do not hesitate to contact us.
