What do you define as acceptable?

My guess would be £299-349 for us. My reasoning: PS3 cost £425 at launch here and this is nowhere near as costly, PS3 will be should be less than half that price by the end of the year, and direct conversion puts these prices at $450 and $530 respectively, which sounds close to the cost of the system.

They will sell it at a loss, like most other console manufacturers will this gen, simply because they will make their money from games, game dlc, virtual store purchases, microtransactions, service subscriptions and premium content, also, adding 4gb of gddr5 only increases unit costs, for Sony, around $35-$44, people act like it somehow bumps the system up $200 or something.

This. As said on the other thread, they'd still take a small loss with that price. About $400 in parts not includng shipping, advetising or actually putting the thing together? It won't be ps3 expesive but it'll be close. They were better off with 4 gig. 4 gig dedicated to games is a hell of a difference to a pc with 4 gig of ram.

BUT that has some beast GPU included... the GDDR5 is expensive, but only enough to bump the PS4 up maybe $50 in cost.

I would like to bet that we see a model cheaper than that at launch. 1 month sig control.

Assuming a $100 loss, a $400 console seems like a good estimate with a $500 "elite" version where they only lose around 50.

Could be even cheaper/less of a loss really. I mean you figure they get a raw parts discount, then factor in that 6 months from now these parts will be much lower in the PC tier then they are currently.

Sony gaming division cannot afford to take a loss on each console sold, unless the Vita suddenly starts shipping 100k+ a month. Its gonna be a pricey piece of hardware, and i think MS will try and undercut them on the price which could be a big downfall for Sony.

Wow, that is a potential problem you are pointing out there.

Plus I've hear the rumors on the MS CPU will process two or four threads.  That will also make a more powerful CPU will it not?

If the machine is expensive, i honestly think sony is fucked. The general consumers are not going to blow so much money on a console regardless of how the fantastic the games look. If microsoft can make a relatively powerful machine at an affordable price. I can see microsoft winning next gen with nintendo at a close second. Sony has to be incredibly careful with the pricing. Really it is make or break for them.

Not just some beast... more like THE beast.

Pretty much the pinacle of ridiculious PC overextravegence.

For a comparison, the PS3 GPU is supposed to have around 1.84 T.Flops.   The TItan more then doubles that.
