They probably won't update the site until end of first quarter next year or possibly beginning of the second quarter. They will get rid of the Sentria IIs first before they even update the site.
Also, the distributors that generally get the new machines first are the ones that have sold out of their stock already and order a new order...
Kirby is a COD company. They will not let the driver release the order unless it is paid in full and no one is going to sit on their old stock. They will deplete their stock first... It's in their best interest.
Now to this... Design...
Someone mentioned why make a powercast type machine since Royal has already done that?
Well that design, ideally, would be perfect for Kirby... You take Kirby's transmission, put it in a design like the power cast but instead of having a brushroll motor, you have the brush driven off of a Direct Air motor, plumb that motor to exhaust into the bag then have a small clean air motor pulling from the bag, add a diverter valve on the back that connects a hose and the direct air pathway that also disables the direct air motor when the hose is activated and Viola! you have a new Kirby..
Wait... That sounds like Tacony's Tandem-Air... Oh, except Tacony doesn't have Kirby's transmission...
Oh well, I guess I'll start pushing this new model as well... :/
