Well I don't think it looks too bad - it is still clearly a Mini and hasn't changed the concept at all.
Legislation drives the changes to a large extent - not just boredom within BMW engineering: eg. pedestrian safety requirements, the headlamps now being fixed - even the fact that the current mini is bigger than the classic
These cars are probably pre-production prototypes as opposed to being off-tool so there can still be tweeks here & there (although the shape will be fixed!)
