I second this, actually. 

didn't forza 4 launch a year after GT5 and Forza horizon this year?  You sig is a worthless comparison.  If it's in response to the other one about Uncharted and Gears I would point out those games launched mere weeks apart so the comparison is much more apt.

Back on topic Sony will not make a tablet controller standard.  They will stick to their basic controller (with some minor improvements like triggers, larger size, and Vita like Dpad) and put it all into the power of the console.  I won't say it'll be "x times as powerful as WiiU" but I remember a breakdown where it was found that, given the prices Sony will get parts at, they can do 1080p 60fps with 4gb RAM and sell the system at $400 at close to cost.  I think their big selling points will be exclusives (like with every PS console) and Gaikai/PS+ (these will be intertwined somehow).  It will be a media hub and they will cut out BC to cut costs.  I like that idea of a dongle with the cell inside to give BC as I would purchase that in a heartbeat to avoid having 2 boxes under the TV (small college living space here).

For that price with Kinect included, I struggle to see it being more powerful than the WiiU really, or heavy heavy losses.

I feel £350 is the absolute max really.

??? Forza 2 was in 2007 and Forza 3 launched 1 year before GT5....don't see your point. Were talking hardware here.

I'm not factoring in competative tactics, because pricing could go anywhere. I'm just using inflation to extrapolate new pricing. 399 doesn't make sense, it's still a posibility, however that console at 399 doesn't make a big jump (compared to last gen). Pricing en power are correlated, due to Moore's Law. 

So if 399 is true it will be a relative weak console.

This man knows

Remember guys, MS might go the "financing" route where you pay a down payment and then pay monthly payments afterwards, with interest offcourse.

or the "cell phone plan" route where you pay for 2 years of Live and thereby you get lower monthly payments

The highest price is still a dicussion with or without those plans. 

Not necessarily. With GPU, memory and other components being cheaper, the console can be more powerful for the same money. I can perfectly be that the 8GB of rumored RAM for the nextbox will cost them the same or less than the 512 MB of the original Xbox360.

Besides, we don't know the real cost ofthe consoles or how much money are MSoft and Sony willing to lose.

wasn't kinect 1 limited in capabilities due to the USB connection (data transfer rate limits).  maybe all they mean is every xbox will have kinect capabilities aka a special connection to alleviate any limiations.

anyhoo, OP seems like nothing but specualation.  and i specualatin taht $400 is a fair price.  i fully expect 2 SKUs though.
