You may have more current info than I do; I'm not trying to be manipulative. I'll admit I have a bit of trouble keeping up but I think there are close to 35 known tablets announced for ARM Based, Atom Based, Ivy Bridge Based, and Haswell Based tablets.
* Windows RT Tablets based on ARM chips - downside: zero backward compatibility
* Windows 8 Atom Based tablets - downside: used today in low cost / low performance mobile products
* Windows 8 Ivy Bridge Core i5 Based tablets released in Preview already to developers - downside: high performance but eats power and has required active cooling.
* Windows 8 Pro Haswell Based tablets - downside: won't be ready until approximately 90 days after October 26 release of other Win 8 products.
The disastrous situation for Intel is if people give up on Windows 8 before Haswell is on the market in products like Microsoft's Windows 8 prototypical Surface Pro product. Lowering expectations of the market that "Yes, there are bugs in this software" and "No, it may not be completely intuitive to transition to."
It does seem Otellini might be trying to alter people's Win 8 expectations with FUD. Not to "sabotage" Windows 8 reception (on Intel chips at least), but to give it some breathing room until they can bring their A-game to market.
But I must admit, I have a hard time keeping up with the half-announcements and turnabout-changes to the announced products, prices, and schedules of release.
