Has Peter released any more Arc4xs after the intial four? Does anyone know if he's planning to? I've not seen any threads at all offering them, unless they've been deleted.
There haven't been any new ones since then. If I have it right, the fifth one is already committed to someone who ordered with the original four and had the order accepted by mistake, i.e. he was at that time promised a light that wasn't available (oops). After that, they'll go up one by one in a surprise announcement system that's been detailed on the forum.
