The only way for this to be true is if you are running the PC games at much higher settings than the console. The following benchmarks show that even the integrated HD4000 can easily handle BF3 at low settings and console+ resolutions and the 8800GTS would easily outperform an HD4000.

I said : " (playable only in tank and jet levels)" , and you are linking benchmarks from "thunder run"(tank level)
. Anything other than this level( maybe train), with only two shooting AI's and performance is unacceptable ( muliplayer basically unplayable). Yo can see in this movie ( from 3:00)

Guy claims it is running at 720p medium . Look at that dips ( or more accurately freezes), look at those shadows, which are somehow much worse than console version. Moreover scenes in this movie are nothing intensive, add few more solders, runing and grenades and you are seeing slide show. Ironically MW3 was even worse.
Today's games are already optimised from the ground up for consoles, that's not going to change significantly next generation - engines are still going to be built on PC workstations. What will change is the PC's ability to rely on a much more efficient API (DX11) than it's had to do this generation (DX9), a lack of requirement to use more power running at higher resolutions because consoles will also be targeting 1080p and most importantly, the far greater relative limitation on power draw for the consoles this time round. I expect all this all adds up to even mid range PC's faring well in next gen console games from day 1 and the gap widening rapidly from there.
I was talking about beginnig of last gen, remember quake, oblivion ports?, Those were pcgames/engines fast ported to xbox 360. Remember all the shock /complaining about in order CPUs, multi threading and necessity of rebuilding engines etc?.And by the time they were somehow optimized, and pc cached up with brute force... This will not be the case this time. Another thing is full switch to console centric development. Look at skyrim which stock version is closer between pc and 360 than oblivion was six years ago...
This time with this console centric development, new hardware which may have strong points where pc's are weak (interposers with very low latency connections/ high bandwidth, some crazy threading like 4 way IBM in P7/a2, edrams. I bet minimum one of these will end up in consoles.) AND add much smaller/ maybe none( from prespective of average pc)power advantage... There are truly none developers interested in truly pushing PC anymore. Another thing, there are surely powerful forces, namely console manufactures which will depend on seeing these boxes as truly next gen by publics end even geeks and may persuade devs to making console versions stand out for some time/not making pc version/making conversion from last gen machines.
Remember pc versions of Just cause, GRAW, not releasing force unleashed,cod 3, bad company "because pc is to slow". I feel that combination of all this, will make few years of nasty ports on PC ( an probably there will be no light in the tunnel for pc gamers like crysis was last time...)Console exclusives level , let alone higher will be no match for small pc devs.
About API. I don't listen too much these reassurances about efficiency, Dx11 pc-console parity? yeah right , just like parity of dx9 with console and pc at the beginnings... Gosh, I remember all these buzzwords : dx10,stream out, SM4.0, geometry shading and fake screens from flight simulator, and now these "monster" can't even play b3 like a console... Few years later we have third generation of dx11 cards and not a single game have efficient, groundbreaking implementation of any features . Consoles will gain new efficiencies too, and soon we will see new excuses about new API needed, and at the same time excuses about fragmentation of pc base which will be cause of not using it...
