Those new filters are your Motion filters, which FCP 5.1.2 will now recognize. And there is one little side benefit to these. Since these are Fx plugs, they are offloaded to your GPU. So, if you have a faster video card with more ram (I have a Radeon X800 on my Dual G5), you will render much faster since, like in Motion, the rendering is graphics card rather than CPU based. I suspect this is a little hint to what we will see in the next rev of FCP (and I can speculate since I am not under NDA and have absolutely no insider knowledge whatsoever... because if I did, I wouldn't even speculate in public).
