Conflicting info on multiple model targets.

Hi,

I've seen a few tutorials on the Vuforia site showing how to track multiple model targets at the same time, but the forums state that only one will work at a time. There's also a video for an early access version that supports object recognition, but I can't find anymore information

Is there a status on what's available or planned for object recognition, and simultaneous multiple model tracking? 

I was hoping to create an application where one main model target plays an animation, and other models can be brought into view to pull up their own animations, or change the main model target's animation when recognized.

If there's no way to get multiple model targets working at the same time, could I achieve something similar using one model target, and multiple 2D targets or Vumarks?

Thanks
