In regards to an economy class footrest, I think the legrest pictured here
is a good idea, definitely better than the little fold down things on the seat in front.
I think the future is going to see a proliferation of Premium Economy classes, as well as increased legroom in economy class itself (as efficiency of aircraft gets better, the costs of having less seats will be countered by this, so air fares will stay much the same)
It is possible we may see full fare carriers offering an economy minus too - sort of a charter configuration, less room, less service, perhaps pay for meals etc, with cheaper fares.
Finally, I think a market that should be watched with interest, though I for one can't predict how it will turn out, is that of all business class private jet flights, like those Lufthansa is operating DUS-EWR, and those Virgin Atlantic had hinted at last year.
