I have absolutely no information... but I think in those 10 there could be some reissues with HD coatings... based on FA designs:
HD D-FA 31mm f/1.8 Limited
HD D-FA 43mm f/1.9 Limited
HD D-FA 77mm f/1.8 Limited
...and how about these revamps...
HD D-FA* 24mm f/2
HD D-FA 135mm f/2.8 Limited
HD D-FA* 300mm f/4 (based on current DA* design)
HD D-FA 20mm f/2.8
on top of some Tamron lenses...
HD SDM D-FA 70-300mm f/4-5.6
HD SDM D-FA 17-35mm f/2.8-4
HD SDM D-FA 35-150mm f/2.8-4
HD SDM D-FA 150-600mm f/5-6.3 (or even better - HD SDM D-FA 200-500mm f/5.6)
aaand might as well rebadge a HD SDM D-FA 28-300mm f/3.5-6.3
That's what, 12 already
But hopefully there will be some original designs there other than the D FA* *85 1.4...
