there's a special edition of the Mathmos Astro Metallic in clear/orange on proidee.de
they dispatch for 18 € to Europe and 40 € to USA!
Good luck with that!
Yeah the lighter finish as you describe seems at odds the central concept of it resembling a solid metallic object when turned off, that and the omission of the logo is probably a deal breaker for me.
Was looking forward to these as well...
