Shortly before Mr. Itirou Makoto Sakurai passed away (January 17th 2011) a DVD by Visual Museum appeared with an interview with him. The DVD covers the second (S54B), third (PGC10) and fourth (KPGC110) generations of Skylines. It could very well have been his last interview.
Just have a look at the trailer:
The music, short skirted female silhouette and montage: it all feels a bit 90s to me… Nevertheless a very promising DVD!
