Recently, Flickr user mikedailly who is described as "Veteran game developer, ex-DMA Design, ex-Visual Sciences. Love technology, but refuse to use a transporter whenever they invent it." posted the original game design document of Race'n'Chase, provisional name of the very first GTA game, from 1995.
http://www.flickr.com/photos/mikedailly/sets/72157602022230830/with/5548285262/There we have some original ideas about gameplay, cities, vehicles and pretty much what the franchise would be.
Nothing too much so far.
But at the very lat page (12) we have for this time only, pen annotations. Nowhere else in the document are anyother. The annotations goes like "Rep 3= ... Rep 2=..." until the end, where it shows "Partition name JRBLIMP" and "Ann = JRHSAIL.BAN" (or something, but this is not the important one). I've googled them both. As for the JRHSAIL we have absolute no result, in the JRBLIMP (google it with the commas for the full word), there are shown 2 official documents only, in the whole web, by the REPUBLICA BOLIVARIANA DE VENEZUELA. One is the official government newspaper and the other an official paper by the ministry of justice.
I think maybe it can be just a coincidence, but:
-the original designs of the very beggining of GTA franchise where only revealed nowadays (16 years later);
-the 12 page document have only ONE pen annotation;
-one of the codes SHOWS NO GOOGLE RESULT;
-the other shows REPUBLICA BOLIVARIANA DE VENEZUELA;
-there were early rumors that the GTA franchise could land into some south american-like atmosphere;
-Rockstar owns the url Rockstar Caracas (Caracas is the capital of Venezuela);
Or maybe I'm just going way too deep in it...we'll have to wait to see it then...
