First for Solid: I think that just first picture is from Swedish rally. For second pic - somebody mentioned Tahiti, and that could be it.
EDITED: and from the pic of discovolante below, we now now it's Japan
.
And now for ZEE:
Be serious please. They are not fake: they are from new movie for the game - showed on TGS yesterday - which is basically the same movie shown on E3 and ECTS, but with few new parts added.
As for the tracks: you've mentioned tracks shown to most of the public so far. During the PlayStation days in Stockholm the Midfield Raceway was aslo shown, as well as Laguna Seca track.
One of the first pictures of GT4 ever was showing Mini driving in some Asian city in dusk. From what we know now, it's probablly Hong Kong. During the 2002 there were mentiong of other Asian cities, and some track located in China could find it's way to the game.
As for the known facts - Paris and London will be in the game, but they are not shown so far. Venice is a deffinatlly newcomer: it will be intresting to see a track located there.
What I can see now is that GT4 will consist of strong number of official racetracks, as well of huge number of real city circuits, located everywhere in the world. Italy is very intresting so far, because as we can see it's hosting 3 tracks: Rome, Citta di Aria and Venice (maybe). Do not forget Rome Night too cause it maybe make it's return in the game. Rest of Europe is also huge with France and GB (probably with few real racing tracks like Dijon Prenois or Brands Hatch or something), Germany (remeber Grundenwald? Also there could be Hockenheim or even Nurbergring F1 cause it's offical that Nordschliefe won't find it's way in the game, sadly) or some other German track.
America so far has New York, Seattle, Laguna Seca, Grand Canyon (in rally section) and maybe some track we don't even know about.
Japan has Tokio and lots of racing tracks (Tsukuba, Fuji, Motegi and there's roumour about Suzuka) as well as few non-real tracks like Midfield and all of the SS night-tracks (SSR11, SS 5, SS Clubman...). Rest of the Asia would have Hong-Kong, China track and maybe some rallies.
And las but not least (this is strictly unofficial): Australia nad beloved and legendary and only and everything: it's majesty - The Bathurst Motherfckn Raceway.
I think we can expect many surprises in next few months.
Both trailers have featured such tacky/trendy electronica... so bad that it's actually cool. 
wow 
Can you?
