I won't speculate, contrary to some tool writers out there in the blogosphere - but instead state facts in a simple and easy-to-read statement: Craftsman. Cordless. Power Tools.
A 20-volt line has appeared at Lowes.com! So far I have found a 1/2 in drill in standard and brushless varieties, an impact driver with 1/4 bit collet in standard and variable speed varieties, a circular saw, worklight, reciprocal saw, multi-tool, sabre saw and an orbital sander.
The drills and drivers are available as standalone tools or in smaller sets (such as a drill and driver together). The set pictured above retails for $449 and includes two batteries, a charger and two soft cases to put all of it in (view it here).
The sleek red and black design is similar to other industry tools which feature a slide-on type battery pack. You can check out some of the sets and tools here.
It doesn't look like they are currently available for purchase... at least they are not in my geographical area anyway. Stay tuned!
Update: my wife informed me that the 'add to cart' feature does in fact work for shipping orders.
