Of course PocketBook will have a 9.7 inch e-ink reader on sale towards the latter part of this year as well.
Jack Flash- as far as A4/larger format devices I only know of one other possibility which i don't think has been mentioned on this site yet. That's the Delta Electronics reader promised for "2nd quarter" of this year using Bridgestone's epaper.
They actually announced 2 readers- an 8 inch black and white model and a 13 inch color model both using Bridgestone's epaper
