There is a fly in the ointment ... Great rouse to stem the sigma tide, but "end of march" will eventually become "delayed due to my aunt falling on her back till late July" ...then release 7 copies in august to keep the pot boiling and mass availability in November or December at the usual high initial price...
This is not cynicism, this is what we have seen repeatedly in the past few release timeline with high end canon lenses.
Well practiced marketing strategy... It is called "stringing people along".
