few things.... a new 8 series would be HUGENORMOUS! think about it... the 6 is a 2 door 5 series, always has been. so the 8 would be a 2 door 7 series. and that is massive. it would be competing with the likes of the bentley continental gt. as cool as that might sound, thats just not what bmw does. there was a prototype m8 made, and was suitably angry and rediculous (go look for the pics! its a red one with black wheels) but i think feasability studies ruled it out, would have been too expensive. thats why they made the 850csi and why they let alpina play with the 8 series. go look those 2 up, the v12's in those 2 cars are very different to the standard bmw 5.0 litre v12
secondly, the numbering system has been scrapped.... or as far as the 3 and 4 series go. from what i've been reading lately, bmw thought it was a very very bad idea to change the names of their top selling range - the 3 series. so the 4 series will not exist, it will just be the 3 series coupe as it always has been.
thirdly, M7. not going to happen. M stands for motorsport, not mercedes benz luxo barge. how are you going to make a 7 series into a racer? and no an s55/65 amg isn't a race car, its a big luxo barge. M7 would be totally against everything the Motorsport division stands for. and thats why there has NEVER been an m7.
