Are any of the major manufacturers looking into next generation models for the standard class?

is there even much room left for developement here? what could really be improved? any tinkering with wing planform and angle of incidence involves trading off either low or highspeed performance, with no overall gain compared to current designs at different wingloadings.

As i see it, the only real improvements available are in the wing root area(like on the new JS-1), and possibly thinner wing sections. but given the wide range of CL these unflapped wings have to work at i imagine that it is harder to make a thinner section work than on a flapped ship.

what do you think?

Was at SSA convention; JS-1 folks seem to be working to extend laminar flow on a new airfoil using suction, and working around the "no active" boundary layer prohibition in FAI rules. If they work it out, the std class airfoil could be mod'd to be most efficient at climb speeds, then have the suction kick in at higher speeds to preserve laminar flow...
