Again, they'll definitely mention it. A lot of the iTablet rumors were from Apple approaching newspapers and magazines.
The market is too small for them to make a dedicated reader--Jobs is right that no body reads when compared to how many people listen to music, watch movies, watch TV etc. at least. I think that's more of what he meant. No dedicated reader will ever sell near the amount the iPod does.
So yeah, it makes no sense for them to put out a dedicated reader given their focus on the mainstream with their gadgets. But it would make no sense not to at last tout reading as one of the many things the iTablet can do. The whole point is that it can do a lot of stuff, so they'll definitely focus some on the reading aspect when they announce it. The question is how much focus they give that aspect.
