There is no 'real' info!
Everything regarding it on the internet is rumour, however some dealers have taken deposits. Having said that they themselves don't seem to know anything about it!
I asked my dealer as soon as I found out people had paid deposits, they said they didn't know anything at all and would not take my money. They assumed the dealers had taken the deposits to give first refusal IF any announcement was made for a new model.
My guess would be Nov '08 for the
JCW if it exists and they wouldn't announce it this early.
