You are right about the Nvidia's G92-mess, but AMD needs a 22nm to call these cards as new generation too.
No company needs a new node to call ARCHITECTURAL change.It isnt NODE change, you can have NEW node and SAME architecture.And SAME node and NEW architecture.
Thats absurd ,and so wrong on so many levels.
Move from Pentium IV cedar mill to core 2 duo isnt an architectural change to you ?
Or from Athlon to Phenom ?

ps.Its gonna be 28nm, not 22nm.
