RSX isn't 45nm yet, it didn't go 65nm until quite sometime after the Cell, so I don't expect that for a while.

No new SKU has been submitted to the FCC or their Japanese counterparts yet, and it normally takes a few months from that until it gets released onto the market, so I don't see 45nm Cell arriving in stores before August at the earliest. It may also get a staggered introduction, so some regions may have to wait longer than others.

it doesnt really matter about the lithography of the chip. The 360 is the only console that this really matters (because of the RROD). Just wait for the PS3 price cut. Beyond that your just wasting your time.

Here's a very old article from December 2007, they say they were suppose to start production in March of 2009, I never heard any news about it since.

"Further along, Nikkei also reports that Toshiba plans to manufacture an even smaller 45 nm RSX graphics chips for the PS3. No details have been announced regarding this, although the report states that the electronics manufacturer will begin production by March 2009."

I'm pretty sure that timeframe would have slipped by now, 65nm RSX didn't arrive until the second half of 2008, nearly a year after 65nm Cell.

it consumes less energy and make it's even more reliable.

The PS3 can't get much more reliable than it is now. But you're right about the power, it really guzzles it. And occasionally, the fan starts hyperventilating and making an annoying sound.

Also dont forget, a smaller chip usually means cheaper console.

Why not... lower voltage = less heat, and heat is the enemy of all things sillicon. You can at least play longer hours before the console gets overheated.

only if the cost of the fabs decrease. however PPC based chips have a long history of having trouble with reliability for a while out of fab shrinks and core speed changes, so sony may not reap the benefits for a while with a high bad wafer count in the beginning.   was always one of the big sticking points when apple used PPC chips.    

outside of that it should reduce some cost, but remember sony sold the right to the production facilities, and we do not know how that altered the cost to produce each unit since they have to pay others to make them now.  

but yes in basic principle it should help a bit

It may just be a quite launch without changing SKU's.... but the 65nm's used now are pretty silent and run really cool dude. Still, if you wanna wait, go ahead. If should be during the second half of the yea.
