Just wondering. I'm waiting for my 5x XR-E module to arrive, but I ordered it knowing that it is sort-of already obsolete. I just wanted something fairly bright to tide me over until 3x or 4x or 5x XP-G modules are available.

But now I'm thinking I should skip the XP-G generation and jump right to a 3x or 4x XM-L module. Don't know if anybody's working on such a thing. I'm guessing that a 5x XM-L wouldn't work because of limited head real estate (55mm head diameter).
