Since the Aeon, Enrique has released a small run of titanium AAA lights, which were priced at $115, featured a Cree 5mm LED, and ran for 60 hours on low and 20 hours on high. I forget the exact drive levels but high was around 20mA. They came with the choice of being milled for tritium. They are phenomenal little lights... although not very bright, as the design goal called for runtime over output.
Last I spoke to Enrique (which was a long time ago, soon after the Makos came out) he was working on some kind of AA light. He hadn't finalized any plans so it's hard to say when it will come out, or even if it actually will.
