Last I heard they were in transit across the ocean. I don't know if shipped to stores means that they are going across the ocean, or if it means that they've landed and are being moved to couriers to ship to stores? I really don't know anything about how Peg handles their supply chain or how fast factory-to-store is for them. I just know their seats are made in Italy.
Babies R Us isn't expecting them in stock before 2013. I don't know if that means that shipment is taking a really long time, or if other retailers will receive product before us. The info provided about the seat was incorrect too unfortunately as it said 20lb minimum for ff'ing. It also said 30lbs rf'ing max, and I sure hope that that was just another typo...
Why anyone would pay $350 for a seat that could only be used rf'ing to 30lbs is beyond me, so I really really hope that that information is incorrect.
The info didn't mention anything about an ARB. I know that the one at ABC kids that was shown on carseatblog did have an ARB, but I don't know if the model shipping will or not - the model shown at the ABC show was a prototype still and things change from prototype to final production model...
I don't think anyone will really know anything for sure about the Peg seat until it arrives in stores.
eta: West Coast Kids is still anticipating sometime in the beginning to middle of November:
http://www.westcoastkids.ca/Peg-Perego---Convertible-Car-Seat and very specifically says that red won't be available until the end of November. That makes me think it's very close to being in stores - but maybe just not all stores will get the first shipment? I don't have any idea.
