Pretty optimistic article. The PS3 won't see 32nm until at least 2010, maybe 2011, let alone 22nm. Last I checked, 2016 was the target for affordable 22nm hardware, not 2011. Nanotech isn't the pushover to bring to market that this optimistic article seems to imply.
Possible technologically, and possible economically are two entirely different beasts. Remember that, using existing tech, IBM was first able to shrink the Cell to 45nm in February of this year (2008)... 18 months before it hits the PS3. Again, stretching the limits of current fabrication tech, 32nm will likely first happen for the Cell in 2009... but given historical creation-to-production trends (like the recent 45nm one), it won't hit the PS3 until 2011.
22nm is a whole different fabrication tech, not merely an advancement like 90->65->45->32 has been. Imagining that it will just fall in line is.. well.. dreaming.
