I'm sure alot of us have been waiting with anticipation for this one.Let's get some samples and/or eval board and test its performance to determine applications that it may be suitable for.
Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit with a sensitivity of 14.375 LSBs per °/sec and a full-scale range of ±2000°/sec
Three integrated 16-bit ADCs provide simultaneous sampling of gyros while requiring no external multiplexer
Enhanced bias and sensitivity temperature stability reduces the need for user calibration
Low frequency noise lower than previous generation devices, simplifying application development and making for more-responsive motion processing
Digitally-programmable low-pass filter .. and more....

The issue for us is the MEMS frequency on some gyros tends to be right in the middle of the frequency produced by multi-rotor helis, the noise from the gyro is just a mess and makes it unusable. There are ways to suppress this noise a bit with hot glue and other tricks such as embedding the AHRS in gel but we did not want to go that route.
As I pay for all the development out of my own pocket, I personally dislike how expensive our AHRS is to make, one failed unit is really a big issue but so far we have no other choice but the adxrs610, it means our AHRS is 3 boards and not one, is not flat and has BGA parts. Using this gyro would easily knock $80 off the price of our AHRS in parts alone, the PCB costs would be less and so would the PCB assembly costs as well.
The post I originally replied to has gone, it was a snarky dig that we always are sceptical of these new parts (I don't really recall being like this actually) but if so, it is for good reason. I would absolutely love this part to be awesome, likely more than anyone else, so far all the testing on other gyros has proved fruitless for us because of the MEMS issue and Quads, but, for other applications and even fixed wing this could be fantastic. Testing would be the way to go as with everything.
Our AHRS will be the last part we make and we are hanging back as there is a chance of some game changer like this coming along that is great for us, in fact it is a certainty something will replace the adxrs610 at some point. If the ITG-3200 is it, the timing is perfect as we have not committed to anything yet.
However this is planned to be an FPV head tracker and I'll quote him "For headtracker this will work quite fine and is perfect solution I would hope but for aircraft I am not so sure.". Seems to back up Melih's thoughts and actual but testing will tell.
Because Open Pilot is sold as close to cost as we can get it, we have room to use high-end parts and have always wanted a high end autopilot and AHRS, we also really wanted a flat AHRS and worked really hard to try and achieve this: http://www.openpilot.org/OpenPilot_FAQ#Why_not_a_flat_AHRS.3F
All this OMG and ten thousand exclamation points everywhere doesn't add much credibility to this thread.
Analog filtering for IMUs is a delicate thing and I believe should be done tailored to our environment, which is full of vibration and oscillations that we cannot control, so we shouldn't try to track them.
The key value is the amount of temperature drift.
Everything else is nearly perfect.
