I agree that there will probably be quite a few deals going on the cameleon 2. I'm happy with my orange one, though. We did consider waiting for the 3rd generation, but a) the reviews on the 2nd generation seem good (better than the 1st) and what if the 3rd has a few teething problems? b) we wanted to get a cheaper 2nd generation as a full priced 3rd generation doesn't fit into our budget unfortunately and c) I'm due in Dec and the 3rd generation is due in Sept ... I was just a small bit nervous about waiting that long in case of delays and problems.
To me, one of the main changes in the 3rd gen is that the carrycot collapses and therefore takes up less space in the boot of the car. We won't be driving around so much and therefore this is less of an issue. I also think (but am not entirely sure) that the 3rd generation has something slightly different (and better?) going on with the brakes.
EmmaNicole - that blue one on amazon seems like a great bargain. I also really like the blue, and (although I prefer the orange!) the blue is a nice classic colour that will probably have a better resale value.
