"Automobile Magazine says under 2200 lbs."
Here's what Car and Driver says. Don't mean to pit the articles against each other but 2200 lbs looks a bit too low to me.

"Unlike today’s Z4, which is powered exclusively by six-cylinder engines, the Z2 will only get four-cylinder power. However, those engines will range in strength from 150 horsepower in base versions all the way to a turbocharged 300-hp, 2.0-liter four-cylinder in the M-tuned version. An expected curb weight of 2800 pounds should allow the Z2 to make the most of that power. "
FWIW, I still like the current Boxster's body better. Not to mention the mid-engine.
