They will maintain Legacy Support for these items. They won't be on their web-site, but you can still order them by calling or E-mailing. They just pulled them off so people wouldn't be placing new orders.
That's my understanding of it anyways. I'm a big B65 fan myself, and was kinda shocked when I heard it too. Luckily I was able to stock up on the when I left Iraq. I have 6 lights that use the B65, and looking at the new RC models, they're not really that much smaller...and with the right drop-in, they're not that much brighter either.
