Yes there will be one, but obviously it will hit the market 1-2 years after the debut of the cabrio. The Z4-35i will be one hell of a car which will force Porsche to significantly up it's power for the Boxster. I wonder if the M version will get the full wrath of the 420hp V8, but I guess that BMW don't want the M3 to suffer so we might just see a Tii version with 360hp or something.
