Funny this thread should start today seeing as I asked about it on the weekend.
The speedster concept apparently was purely a design concept during the initial Convertible project, but the benifits of a 4 seater over the 2 was chosen and the Speedster taken no further.
However MINI are always looking at potential future concepts so there is nothing to say that it will never appear but it is not on the current design plan as a future model.
Now my take on it:
For any company to make a product it would need to have proof that it would add sales rather than split sales between the new product and the existing range, which in this case the addition of a second convertible model would only steal sales from the existing model. So why invest in a new product which is not going to gain you any added market share, it would be more wise to invest in a product that is going to get your into a new sector and gain you a different customer
