Actually, I don't think cost of development for next-gen will be that huge of a leap (some estimates put it around 15-20%) - most of that transition has already been done in jump from PS2/XboX/GC to current gen. And "all real-time" engines like UE4 will just make development even easier for artists than it is with current engines, so lot of savings there (very nicely explained in UE4 tech demo video).

As for power of 720/PS4....there has been some rumours lately for both of them, 720's being bit more realiable I'd say - if final specs are anywhere near what those rumours are stating we might very well end up seeing difference of some 4x in power beetween (at least) 720 and WiiU. But since I was talking about physics, I'll just post comparison of e6760 and equivalent of rumoured 720's GPU power (though only one test, SPH fluid simulation - fuild simulation is exactly the stuff you have see a lot in Borderlands 2 PC PhysX version):

10x - shocking, right? Now I don't know how this translates to other GPU physics based tasks, but if you look that RayTrace is some 12x times as powerfull....that's why I think that major developers might have problem porting easily 720/PS4 titles to WiiU once they get the hang of their power.

But 15-20% more will elevate games with the same percentage. So games will be at least 69 euro's (don't know the retail prices for games outside Europe) so that's not something to take lightly.
Also, what does the UE4 cost for dev's to use? Epic themselves will be able to create nice and shiny games which will probably be exclusive anyway but other dev's will have to fork out money for the engine. I don't know how much the UE4 engine will cost but I'm gonna go out on a limb here and say it's not particularly cheap. The same goes for other 'Next-Gen' engines.

As for the rumored 720 GPU, could you give me a link please? Not to say your wrong. I'm Just interested.

I can't find the link to site where I picked up rumoured 720/PS4 rumoured specs (it was some German site), but it was more or less detailing diagram in following http://www.pcmag.com/article2/0,2817,2405922,00.asp, with some additional info, crunching numbers to equivalent of slightly overclocked 7850. Some other rumours for PS4 (http://www.vgleaks.com/world-exclusive-ps4-in-deep-first-specs/) are also putting it in this range, some even mention downclocked 7950 type performance. That's just few I came across in last few months, so either 7850 or 7970m (which is downclocked mobile 7870) could be  decent starting points in lack of exact specs, considering they are around 8x (indicated next-gen projections) more powerfull than current-gen GPUs.

I have a hard time believing the PS4 and XBox 8 will feauture such powerful (and powerhungry) graphics cards. The diagram shows the XBox will use around 120 Watts total with the SOC around 50 Watts. That leaves less then 70 Watts for the GPU. A 7770 already uses 80 Watts of power.
And then there's the cost. Every rumor suggests the new XBox will be packaged with Kinect 2.0. I don't know what price Kinect 2.0 will be but I doubt it will be 50 dollars or less so unless Microsoft will release the XBox at a price range of 499 dollars (highly doubtful in the current market) or higher I doubt the new XBox will feature powerful and costly hardware like the 360 did at the time.

As for the link to the supposed PS4 specs, I don't believe them for a second. DirectX 11.5? The Tahiti supports 11.1, next up is DX12. A Graphics card of at least 399,- in retail? That's about the same price as the 7800 GT in which the RSX was based. If that rumor is true the PS4 will be the PS3 all over again. They could sell it for 499,- and still make a massive loss. Sony can't afford that.
And then there's the fact Sony has already said they wouldn't be gunning for the most powerful console next gen as that has only cost them money.

So I doubt the XBox and PS4 will use anything close to the tahiti cards. Even if they're underclocked a card based on those chips will require at least over a 100 Watts of power. That doesn't fit the diagrams 120 Watt of system power at all. An underclocked 7770 though (or an overclocked 7670 or equivalent) does fit the diagram. Those will still be more powerful than the rumored Wii U GPU though but nothing like 8 or 10 times more powerful.
