There is no official information available on the next release at this time. We were shown a couple of ideas that were in the works, one being an asymmetrical, but it was being looked as high end piece.
Like I said though, nothing is official enough to be confirmed at this time and anything could change at a moment's notice. Right now we're riding the wave of success that is the new Maximum Altitude Pearl. It's not an asymmetrical but it is an amazing ball!
