Do you think it will any time soon?  I'd say expensive dinghies (especially single handers for Dad) are one of the minor casualties of this economic downturn, for club racers anyway.  I very much think the landscape of the sport as we see it will change semi-permenantly into more club-centric with holiday top ups and as such the better club race boats will become even more popular as they deliver good racing and a safer investment.

So yes, we'll all get to sail a new trap and/or asymmetric kited boat, but we'll do it on holiday, at a beach somewhere warm and sunny.  We won't bother trying to make one work in a crappy handicap race at a shifty duck pond, no matter how RTC friendly the demo-boys say they are and no matter what changes the RYA think they're making to the PY system.  

As a general rule of thumb, if you want a trap singlehander with a kite, I really can't see what's wrong with the MPS.  Plenty of 65kg+ folks have sailed it; it just takes time, practice, dedication and ideally, folks to learn from, either at one of the emerging club hotspots, or on the circuit.

Farr 3.7 with a kite... trap for when it gets windy and too much like hard work.

You'd definitely need to allow yourself to use the kite when racing, and btw, it'd get a bit of an advantage on PY as all the boats sailing at clubs which submit returns (thus adjusting the EN) will probably be being sailed sans kite, thus slower than Lasers downwind.

Me neither.  But having sailed one on open water up a long beat, I can assure you they don't feel like great upwind hiking boats either, even if that does sound a little oxymoronic.  I would liken the experience to downhill skiing without the ski pass.... it's a long, slow and painful walk uphill for the 5 minutes of pleasure coming back down again.
