Note: long Eiger and London courses are pretty much confirmed so I included them (I believe both of them, or at least one, are called "short" in the Japanese version of Prologue, and there are areas for them to extend and return back onto the short circuits). Also, we've seen the pits and main straight grandstands of the GP Strecke Nurburgring so I included it as well, plus I made some assumptions where some tracks might have a reverse variation as well, although who knows, maybe some of those won't. Stelvio Pass we've seen in the Toyota FT-86 video and the one under it we saw in the Ferrari California video back a while ago.
There's no way there's only a few more tracks to be confirmed since you'd need about 20-30 variations between them which is just ridiculous, especially since the average variation per track on this list is 2 or so. Keep in mind this list doesn't even include so many traditional GT courses like Trial Mountain, Deep Forest, Grand Valley, etc., as well as traditional real courses like Laguna Seca which are very likely to be in.
There must be many tracks to be confirmed, and if you're worried since we haven't seen much at all yet, well, how many cars have we seen? Other than Prologue we've seen probably 30 or so cars at best. Hell, even if you include Prologue we've still only seen around 100. What about the other 900? Are they not going to be in the game? Of course they are, but we just haven't seen them yet.
It's the exact same thing with the tracks IMO. PD is being very secretive about GT5 for some reason and we really don't know much at all yet. Also keep in mind how Kaz said the E3 trailer was such a tiny part of the game and that it was so massive he could hardly explain it. We really haven't seen much else since then so there has to be a lot more for us to see between now and the release, including tracks, cars, and features like a livery editor, etc.
IMO 20 locations means literally locations, as in Japan for example (which includes Suzuka, Fuji, Tsukuba, and maybe GT street circuits like R246). Therefore we have a lot more circuits to see and a few very likely ones would be Spa, Monza, Laguna Seca, etc."
