I don't know about the Metz situation. However, one of the
big problems with "high speed sync" flash is that they are
battery hogs. I initially assumed that the wizards would
mitigate the battery sucking problem enough to produce a
more powerful flash, but it may well be more problematic
than it seems. If you think of it, the flash has to pulse
repeatedly at a constant color temperature for a relatively
long time (about 1/40 seconds). I believe I recall reading
somewhere that other manufacturers' high speed sync flashes
drain batteries quickly as well. (Perhaps users of other
systems which carry these flashes can comment.)
It may well be true that to produce a practical flash with
professional power, a manufacturer may have to employ a
seperate high energy rechargeable battery pack similar to
those employed by Norman, Sunpak (for the J120) or Quantum
(Models T2 and X2).

Yes, as I pointed out above it pulses in micro short bursts
over a 1/40 second time span.
