Just read an Auto Express article on the forthcoming MK VI GTI.
For what it's worth, and from memory only (!), the new car will be due in the UK in Autumn 2008 and will feature a revised corporate grille with two horizontal bars in it. It will be a streamlined update of the existing body, which doesn't look that different to be honest if the images are to be believed, featuring the same high waistline and C pillar look. The car is to be introduced earlier in the Golf evolution cycle because the new model will not be so complicated to build.
To reduce production costs, the suspension will feature a simpler multilink system which will also reduce build time. The DSG wil feature a new 7 speed ratio box

The R32 will retain the 3.2 engine and not the 3.6 which is coming in the Passat

.
We'll have to wait and see then
