Very interesting, not a lot of details but some good stuff. For example it seems we aren't getting a full-featured IDE which is a bummer partly because that means no official debugger support.
I had to skip the Atmel stuff in the middle, not enough bandwidth, but Massimo's bit about open source was interesting and I sympathise with their predicament whereby they do months of work and someone clones it in a few days. I will never buy a $10 Chinese clone for that reason. I currently have one official board and one Australian board. I will buy a clone from someone who has given back to the community and will of course continue to buy official Arduinos, in fact unless there's a compelling technical reason to buy a clone I will only buy official boards in future I think.
