Some highlights:

So, I shot a simple scene this evening: a sparkler, my Sony PMW-EX1 (overcranked to 60fps), and the Shuttle.
The differences are pretty pronounced, there’s slightly more detail, less noise and less compression artifacts in the uncompressed footage. It’s also pretty huge, see previous post.
I think the footage looks nice and the Shuttle is nice to have, but for many shots it’s probably pure overkill., e.g. interviews or simple registrations. It might be nice for (reflective) water, shots with lots of motion and scenes with little available light.
Like, for instance, a Blackmagic Design HyperDeck Shuttle. After waiting for it to become available and then waiting a little bit more for the (custom made) cables to arrive, I’m finally ready to go out & see what’s what.
Initial findings: firstly, uncompressed HD video is, unsurprisingly, insanely large (34:16 seconds @ 1920*1080*25fps = 4.868.530.254 bytes) and secondly, 4.868.530.254 bytes via USB 2 = no fun. Premiere Pro CS5.5 however seems to have little trouble handling (a few of) these files.
This post will be updated with more info, images (still and/or moving) in the very near future.
Spot the differences! I know it’s only an incremental update but you might have made some effort, Adobe.
Anyway, in my opinion the new Warp Stabilizer alone is worth the price. That, and the Mercury Playback Engine is supposed to be improved.
