Hi Nair,
We don't have any plans for the release of a new design at this point.
The RPL is doing very well, I don't know of any portable laser of this medium/small size that can perform as well as it does. It several itterations to get the RPL to the level of product I would even offer my customers. It keeps getting better, with longer run times and tighter divergence.
I am beginning to offer a 15mW RPL-Blue and within the next month will offer some lower power PPL models in the range of between 50-100mW at a target price of $150-$225, we shall see what kind of deal can be made.
Keep watching, we're going to start having all kinds of special offers, some will last one day, others longer, and some just for the active CPF or laserpointer forum members.
