Good info.

Is there a way to see the stats on the simulator?

Yes - Same way you can on a dev alpha. From the main menu swipe towards the middle from the top left corner.

Is there some documentation on how to read and interpret all those numbers in the stats overlay? e.g. what are the 2 or 3 different values given for some of the parameters? and what would be some thresholds to watch for to figure out if your app is a reasonably good 'citizen' ?

Not that I'm aware of. I sent out an email to a few people here at RIM to see if anyone knows more than I do.

In general FPS is going to be your best indicator and I would shoot to keep it above 30FPS.

Also we will have Scout support when the runtime is updated - http://gaming.adobe.com/technologies/scout/ 

Personally I can't wait to start profiling my BlackBerry 10 apps with this.

Is Adobe Scout support for BB10 out now? Is there any way to profile my BB10 app's performance with it? It's an AIR app, of course. I've just started using Scout & think it's amazing. Thanks!

Adobe Scout is a part of a newer version of AIR. Once we get AIR 3.4/3.5, then we should get support for Adobe Scout. You can use the current profiling tools in Flash Builder.

ETA??? 

We really need Stage3D support and are hoping  you guys will have it by the time our first game ships in April/May.

GPU Render mode needs fixing too... In PicShop on Android & iOS, I use GPU Render mode to do an easy 60fps, it's beautifully smooth and buttery. But on Playbook/QNX it's totally unstable and crashes constantly, forcing me to use CPU render mode, and get middling frame-rates.

I'm secretly hoping that some much needed improvements for GPU Render Mode are coming as well. You seem pretty down on it in your article, but in fact it's a true beast, and the tricks to pull performance out of it are super easy:

It does support Filters, sorta, you just need to do some tricks:

1. Apply filters to off-stage DisplayObject, and bitmapData.draw()

2. use bitmapData.applyFiter() on an already cached display object
