I'm not sure about adding decimation mainly cause I don't know of any real improvements to make over decimate, aside from maybe using 3 sets of offset blocks at +16x, +16y, and +16x+16y to better catch small movement (but it would make it slower) and making a small change to mode=2 decimation to fix an inherent limitation that can cause jerkiness when going from panning to still and still to panning scenes. I don't think TFM will change TDeint much at all, it will still have the option to weave fields, but I will probably turn it off by default and make the defaults of TDeint better for true interlaced material as opposed to how they are atm with the defaults being a compromise between settings for several different types of material.
