Word on the street--or from Spilling The Beans, the shopblog for Brookline, MA's Magic Beans, anyway--is that the US models of the Quinny Buzz will drop in May. The Maxi-Cosi car seats will drop in June. The Zapp drops later in the summer, like July.
Plan your strollershopping accordingly. [Or, you know, don't because dates like this slip all the time, cough cough Orbit cough]
