I can confirm Glossy postcard: tried to order some for myself last week and was told by Silverprint(.co.uk) that it was discontinued. They are sending Pearl, but I did not know if that is just old stock or new. From what you say, looks like it is indeed existing stock - get it while you can....
Did they say if this was a permanent situation? It may just be hiccups while things are sorted out at Ilford ("The Photographer's Guide To Clutching At Straws" is one of my favourite reads at the moment....).
Ho hum...
Bob.
