High-quality, but only stripped down version

As GT4 GT5 is also of high quality and comes with respect. The graphic highly Classic therefore. Generally, however, you should take the word 'Proloque' in the title very seriously, otherwise you will experience a disappointment: It is just 'only' a previous version with absolutely limited functionality - the word 'Demo' could have been used instead of 'Prologue' also , So there are only a few routes and only a fraction of the vehicles, as known in GT4; Further, in the Prologue version neither tuning nor licenses and no driving missions. Also on rally tracks and cars you have to do without. But you get a taste of what can wait nothing around too long in coming, hopefully, that the final version. And what is already in the Prologue version, raises a lot of fun. Great, high-resolution graphics and - as otherwise usual from GT - an impressive handling of vehicles. The absolute highlight among the (still few) changes, in my view, the possibility of drifting in the curves - just great! Oh, as a new track is 'London' added.
I'm just curious if the final version of GT5 (apparently supposed to appear until the end of 2010?) Actually will offer as much as GT4 cars and tracks (I have read something of more than 1000 vehicles ...). Honestly, I can not imagine that such an extensive amount of information on a single DVD fits me. But wait and see and look forward ...
