Welcome to MobileRead, BuAba!
I don't have a Cybook, so I can't answer your questions about that, but as for new e-reading devices that might be coming out, the makers are notoriously tight-lipped about forthcoming devices. Occasionally we get wind of one beforehand, but it's very much the exception, I'm afraid.
So the short answer is that we don't really know of any specific device that might be coming out in the next year, let alone enough about its specs to give you an opinion that's worth much.
What I suggest is that you look at the ones that are out now and decide if any of them will fit your needs/wants sufficiently for you to pay the asking price on them. You can spend your whole life waiting for "the next one" or you can go ahead and get something that you can use now, balancing the use you'll actually get out of it against the knowledge that other models will be coming along eventually.
