Ford US has secretly developed a small stroke V10 using the 4.6 sand casting and joining 2 cylinders onto the V8. However its very prototypey at this stage and a bit of a frankenstien. Ford OZ could try and source it, it will apparently be used on the new Cobra.

the V10 would be narrower than the 5.4, and shorter than the I6.
Good to hear they are keeping the 6's. Im not impressed with any of fords V6's so far... None are suitable for Territory or Falcon.
Instead of tooling the I6 line for V6's they would be better off making more I6 variants. Such as a alloy block, a shorter stroke varient (3.0-3.5L).. From this they could make a V12, (~7.0L would be nice. Use it in Lincon sedans, LTD, big american SUV's).. It would cost the same or less as turning it into a V6 plant and would add some niche engines for Ford.
So lets say the V8 and I6 stay. That means the front of the falcon can't change that much, those engines still have to fit.
looking at other automotive developments I guess we can expect:
-Better pedestrian safety
-Better crash safety
-LED lighting for indicators, brake etc lasts longer, looks modern, higher visability, faster, don't need fancy reflectors as much which means less cost when going to new model.
-HID lighting (I'm guessing eventually it will happen as a option, Ford loves options they make money).
-New gearboxes (yippy)
-Weight loss through stronger materials, lighter materials etc (I would say more thinner high strength steel materials than say alloys)
-Improved readability of instruments
-Improved economy (from weight, reduced drag and engine/gearbox improvements)
-Forced inducted V8 (where else is the power going to come from)
-Styling improvements (more aggressive?)
-New Colours (obvious, some old colours may resurface)
-New Wheel designs (obvious)
-Improved braking (ventilated rears? Bigger fronts?)
-Lower NVH through design and insulation (better tyres, using tarlike products)
ie the usual stuff.
