This might be interesting for a handful of reasons.
The mock up looks beautiful, assuming the publisher can get the project off of the ground. The price, as with most Latin editions, is absurd and will likely prevent wide diffusion.
The publisher, so far as I can tell, is a "Sede." That only increases my interest in learning how many of these will actually be printed and what churches will have them at the altar, or at least in the sacristy.
I'll be honest: if this thing sees the light of day and is readily available, my jaw will drop.
