Motor mount forward has been mentioned in the released info.
New material possible.
New internal ratio I think unlikely but possible.
Even if the diff ring gear is enlarged - I think maybe/likely as mentioned earlier - doesn't automatically mean an internal ratio change.
Currently it is 37t for the pulleys, my guess is a move to 39t (like the TRF503) or maybe 40t (like the BD7)
