MotoringFile provides this "confirmation" from its "unofficial" source:
Just a few days ago we heard that the Paceman would likely not live on past the current generation. Now we heard from a very reliable internal source that it may do that and grow to accommodate more utility.
Speaking of the Countryman MINIs is planning on making the 2nd generation heavily influenced by the Dakar-winning competition car as a more ruggedly styled crossover. The Paceman on the other hand will be more urban oriented in design and feel decidedly more sporty.
If this news is correct (and this source typically is), the Paceman will join the five door hatch, Clubman and Countryman as the fourth [sic] four door MINI.
