Last I heard, and this is going back nearly 18 months, both of them are/were due to go into production at Oxford later this year... PistonHeads Headlines - MINI Roadster Revealed
Since then however, there's been very little buzz about either of these new models. I think people are waiting for the official word from MINI before getting excited?
I find it strange that only the coupe gets the 211bhp JCW engine, while the roadster will apparently only be available in regular "S" guise. If a JCW variant of the roadster was made available, I'd definitely be interested (although from what I've seen so far I dislike the manual fabric roof).
There's no way that the coupe will start at $19,900 though. The base Cooper S starts at $23,700 and the JCW hatch with the same engine starts at $29,800.
Also take into account that the base S convertible is $28,550 (with the JCW variant coming in at $35,000) and these new models are both likely to be in the $35k+ range if you ask me.
EDIT: Thinking about it, if these new models are available in Cooper (perhaps even One) guise, the $20k price becomes more realistic. The fact that these prices have been bandied around somewhere suggest that this may actually prove to be the case... not to mention the spy shots which appear to show the coupe in Cooper guide.
