This is standard fare on trade shows. It is probably done, one hopes, not as much to outright mislead as to avoid embarrassing malfunctions on the show floor.
I think it is in good faith - they aren't intending to lie or deceive, but it's show and tell time and the product isn't ready. I still think it goes against the spirit of a tech demo and is pretty dishonest. Intel have very aggressive schedules lately, so this isn't surprising.
That is also why they knowingly ship broken chips lately:

I'd wager half the products at CES are running canned demos in flash. It's an open secret and everyone does it.
