I emailed them asking what all of us r wondering and here is their response:
Thank you for your recent e-mail. It will be the pro 2 series. I
haven't heard when they are coming out yet. I would just keep checking the
web site as soon as we know it will be on there.

I hope you find this information helpful. Should you have any further
questions or concerns, please do not hesitate to contact us at this
email address. (Please be sure to copy all previous emails into any

DID YOU KNOW that our web page has a Mechanics Corner and an Online
