We tried to order one for a customer through our distributor Wynit, who said they have one left and Epson has told them they are no longer available. The fact that B&H also indicates "discontinued" means they cannot order more so they are limited to what is inventory.
I'm sure Epson has retooled the 3880 line to make the new p800, so no surprise they are discontinued. There are still quite a few to be found through various dealers.
Epson typically doesn't make a real public announcement of stuff like this, they just let it be found out through the channels.
