As much as I'd LOVE to get my hands on another 26650 light (MUCH longer runtimes than 18650) I'm going to wait until Wayne, the proprietor of Skylumen.com gets his hands on this light and mods it. He's a Lumintop direct retailer, who mods factory lights- most of his products are ala Carte, with different emitter and brightness options. If you're in the market for a light, give his site a look - he does GREAT work!
And, as an aside, this is a good price on this light, btw...
