Did you mean the Talon SRX? It says on the product page it's a drop in replacement for the Victor SP, but it's size the same as the SRX. If it was a drop in replacement for the SRX, it should have CAN, but it's too large to be a "drop in" replacement for the SP.

I actually meant the Victor SP. It's about the same width, so it should fit in with some clearance for most people's mounting configurations, provided you didn't rely on the length too much. I'm not sure why one would want this though, but if I were to guess, they're just trying to establish a standard for motor controller sizes.

Did anyone in the beta get offered to test these? If so, could you try some tests to figure out the general quality of the new motor controllers?

We haven't seen any for Beta Testing.
Beta Testing this year has been on the software rewrites and updates.

Yes, just to be clear, navX-Micro is definitely legal.

Rather than connect to the MXP port, NavX-Micro connects via USB and I2C and is software compatible with the NavX-MXP libraries. So it's a drop-in addition if you already use NavX-MXP.

Navx-Micro is a great option for teams that have already populated the single RoboRIO MXP port with another MXP board, need a second IMU for turret angle or robot arm angle, or are teams with a limited budget. The 2017 NavX libraries will support multiple NavX-family devices, so you can use both NavX-MXP and NavX-Micro on a single robot - even at the full 200 Hz update rate. And even more, there's upcoming support for video processing latency correction to be released soon.
