When the slim arives what will happen to the fat ps3, will the remaining sell like hot cakes? and if so how much do you think they will sell for, cause my brother said when the slim comes, he will get the fat one because he thinks it will be cheaper. I think it will be about £230

I hope not i want one over the slim.

hmm slowly fading out yep.
thats was happen last time with ps2 slim-
fat was sold along site until the stock was completely sold.
if you want one get the money and grab one as soon as you see it.

the news one 80gb are very reliable both 65nm/65nm and maybe 45nm cpu.

I would imagine they will be phased out like the B/C consoles were when Sony introduced the models without this feature and it was sell until there were no more!

Only tomorrow now, so will see what Sony have in store for us

Seems likely, slim should be cheaper to make so there's no reason to continue production of a costlier and less desirable model.

how much could you see the old one selling for? and will that also boost the sales

I'd be really surprised if Sony continued to sell the "fat" model of the PS3 after the Slim introduced. Usually only portable consoles sell multiple types of the same hardware. With home consoles, usually the newer model replaces the older one. I highly doubt Sony is still even manufacturing "fat" models at this point. So if you bro wants a fat, he should buy right after the Slim is introduced. Retailers will most likely cut the price below the Slim model to clear inventory.

And as Sony has always said there would be no price cut, maybe they'll just phase m out...

can anyone refresh my memory?
What happened to the older models when the PS1 slim and PS2 slim revisions were introduced?
Did the price officially change or were they just in-store discounts...
My memory has taken a hit from too much vacation

It should. It is overweight and portrays an unhealthy lifestyle for future consoles.
