no need to worry.

i've attended all of them, and the content is not 'going down' at all. last year was a sort of hackathon where we all worked on projects with the help of ssolie, broadblues, and others. this year there were tons of topics over two days, including:
- walking through the API changes introduced with AOS4.1 final edition
- creating filesystems with the vector-port API and diskio.library
- new opportunities introduced with the new console.device
- walking through code examples using the new extended-memory objects
- very, very cool walkthough of composited video capabilities
- how to use the new BOOPSI menuclass
- an in-depth discussion of the new unified graphics.library
these are more advanced topics than in the past, and every year the topics get more in-depth. so we all learn a ton and have a great time. usually key developers are a part of it; last year it was andy broad. this year it was rene olsen. so although the wiki may not reflect it, we get through a bunch of useful material.
there's a reason i try and get folks to attend every year. it's worth it. ;)
