Anybody attending Apple's Tech Talks in Hamburg? Would love to get in contact with other cocos2d developers.

I went to the UK one today, and was really impressed, especially as it was free, including the lunch.
Found the OpenGL ES talks the best, I thought they might be too complex for me, as I haven't done much with it directly, but followed along quite nicely, it seemed cocos2d has taught me alot about the concepts along the way (thanks for that), and the talks helped explain some of the inner workings.
Hopefully they'll have videos of the sessions available for all developers soon.
I'd like to check out some of the other talks I missed.There were quite a few tips mentioned. Alot of which already seem to be used in cocos2d.
One I don't think I've seen mentioned, or maybe I just missed it, is thumb compilation on the newer PowerVR SGX (3GS etc.).
For apps with high floating point calculations they recommend it be switch off on the older devices (as is already done by default in cocos2d).
But they recommend it be switched on for the newer chip, as it has can handle FP calcs quickly (& a few other pro's were mentioned, although I stupidly didn't note them)
He showed a way to use 'Build Setting Conditions' in the 'build' target info window, so you can set this for each GPU. Although I've just had a quick look, and only get options for Intel, Intel-64-bit, PowerPC & PowerPC 64-bit using xcode 3.1.4. But I'm probably doing something wrong.
Has anyone else seen the OpenGL talk where this is mentioned, and happened to photo the slide with the pros & cons of this?
