Perhaps a bigger question is this: if a next-gen

TV was launched with the Tablet, which device would really grab the BUYERS attention? My thinking is that a next-gen

TV is much more interesting for mass market buyers than a Tablet.
Sure the Tablet would be most of the "wow!" as it would be entirely new. But as is evident in many Tablet threads, the non-fanboy crowd keeps having trouble figuring out how they would use it, why it would be preferable to a laptop they might already have, and so on. Mix that "functionality" problem with the estimated price of $799-999, and you get more of the "if it's that much I would just buy a laptop instead" and similar feedback.
A next-gen

TV doesn't have to go up in price at all, yet can step it way up in terms of capabilities. We see from many competitor boxes that you can put 1080p-capable hardware in a box and sell it profitably for a lot less than

TV pricing now. For the "it has to have a BD player" crowd, we see that BD players using 1080p playback chips can be put in a box and sold for a lot less than current

TV pricing. For the "it needs to have DVR functionality" crowd, ditto.
But more importantly it seems to be a lot easier to imagine a much bigger market of interested buyers for a cool, cheap(?) device to hook to the HDTV vs. a market who will pay up much more dearly for a device that they can then pay up some more to purchase e-magazines/e-newspapers (to which they may not be subscribing now), instead of buying that same content on a laptop or iPhone they already own.
I strongly believe the next big thing from Apple is a next-gen

TV rather than this Tablet, if "big" is measured by how many buyers will subsequently buy it. I'm somewhat interested in both, but I see a next-gen

TV as a no-brainer, while the Tablet seems like a "maybe" at best.
