Here's the video:
Well it does seem to be pretty amazing in that it looks to be more or less APO and to also have zero hazing and full contrast and detail at f/1.4 under any lighting AND even into FF corners is pretty nuts.
Man $4000 though is still rough. At $2500 they may have sold some good number, $4000 will cuts sales a lot since that is just too much for many for such a lens no matter how amazing. Still it will get some sales since the performance does seem way better than any other current 50mm (I've never really had a look at the Leica stuff though, which have been said to have been the best up to this point.)
OTOH Canon managed to make a complex 24-70 2.8 more or less APO so you wonder if they couldn't match this and with AF for say $2600??
It makes the 1.2L optical performance look like a total joke, same for the sigma 1.4 and all the older types of course too.
