If this is true its indeed great... the iPad Air 2 is going to be a total iPad 2 like device ie. a model with some legs in it.
That also means every other year, is when you should really buy your iPads.
iPad 2 - fixes all the 1st gen stuffs
iPad 4 - retina display + performance boost over iPad 2
iPad Air 2 - newer lighter than Air 1 + performance boost over original Air
The iPad 3 and original Air are rather underwhelming releases since they didn't really change the performance much - the 3 is just an A5x, the Air was just a reskin for a newer shell. The poor original iPad suffered an early demise much like the original iPhone.
I'm still going to wait for a Black Friday kinda deal myself though. By then it should be confirmed for sure.
