Did they stop releasing this series of steels on part 7?
There's what I call an American series, the best looking, with proper titles, like Fast Five (copped out on "Furious 6", added 'Fast' there), still being released, got all 9.
Then there's what I call FilmArena series of steels (although they were released elsewhere), the simplest looking, just huge digits and a colored accordingly car. Got first 8, 9th probably is coming.
And besides the stand-alone steels for every part, sometimes two, there was this what I call German or European series, somewhere between the FA and US ones in terms of quality. Still, I bought all, even that 7th empty steel, but don't see an 8th anywhere...
