Yeah right ... not
@The future iPad will not be backwards compatible with the old iPad so this folio/kbd unit will not work with it anyway.
Its a bluetooth keyboard and unless they change the bluetooth stack for some future non-backwards compatible protocol standard (which is highly unlikely) then it will work for years to come ... this has been the case with Macs ever since they included bluetooth keyboards as an option in 2003.
Plus if you have any real inside information on future iPad's then you could make a lot of money out of that ... but I'm guessing that you're guessing and badly at that.
