Are R200 resolution limits surmountable?

Do R200's resolutions & frame rate limits (@60FPS depth at 480x360, color can be 320x240 or 640x480;
@30FPS depth at 480x360, color can be 320x240, 640x480, 1280x720, or 1920x1080) reflect a hardware limitation? Or is it possible that with future driver / firmware updates we'll be able to get higher resolution at 60 fps on the color cameras, while still outputting depth at the same or better resolutions & frame rates?

It was mainly restricted by the USB 3.0 bandwidth.

The SDK supports:

4 * 1920 * 1080 * 30 = 249 megabytes

The SDK DOESN’T support:

4 * 1280 * 720 * 60 = 221 megabytes

This doesn’t make sense. Why is support for 720p at 60 FPS not an option?

Thanks, David! Gregory, those are my thoughts, as well:

720p at 60fps, which is not supported, has a lower bit rate than 1080p at 30fps, which IS supported.

Is the low limit on the 60 fps resolution enforced for some other reason, besides USB 3.0 bandwidth?

I think it is a good feature request and I will talk with my colleague. Thanks!
