Why has Cessna taken so many orders for the Skycatcher by now? Because it is an LSA in market where there are not that many American players yet, because it's built by Cessna (a name which rings a bell with most people previously unrelated to aviation) and because owners will benefit from Cessna's huge sales, maintenance and flying school network!
As such, European LSA manufacturers will need to dress up warmly if they want to enter or stay in the American LSA market, even though their products are superior in terms of performance and economy (remember how "succesful" Diamond were with their Rotax-powered Katana in the US?)!
Have a look in the latest issues of Flying to understand the average US pilot's perception and understanding of that type aircraft. Its editor essentially recently stated that it was invented by Cessna, thereby totally neglecting the thousands of Tecnams, C42 and CT's flying elsewhere in the world.
It is not a 150/152 replacement, because it is an LSA and not a fully certified aircraft!
By the same token I doubt that we will ever see the Skycatcher in Europe. It's too heavy to qualify as a microlight and Cessna would not bother with the costs and trouble involved in certifying it as (e.g.) a JAR-VLA just to sell a couple of dozens per year in Europe when they sell hundreds each year in the US (I believe they currently have orders for almost 800). Even if a European LSA category (1:1 comparable with the US one) appears one day, who would want one? A Remos G3/600 costs about the same, has much better performance and useful load, and uses less fuel!
Great marketing move by Cessna, but not of interest for European pilots.
