bla...bla...bla...disappointingly light on details
They still haven't confirmed the front will be the same as the current m3 saloon and not some fucking god awful monstrosity like the rest of their new models.
Maybe it's because they want to fill up the order book first.
It's definitely the new grill style - it's not being released for two years.
Only way it won't be is if sales are so catastrophically shit on the upcoming 3 / 4 series that they have a massive u-turn which is near impossible considering how far out car manufacturers plan models.
By rumour mill, I assume you mean announcement...
