I think this is very interesting and extremely fun to speculate. I did think that the invitation was a bit strange when I first saw it given Apple's tendency to subtly hint at new features. The invite shows an iPad. Obviously people can assume that the announcement will be iPad related, and obviously iPads have touch screens. Why waste the extra copy?
Maybe the product will be available immediately for the media to test. But this hardly seems revolutionary, given that this ALWAYS happens at their media events.
Further hope for haptic technology can be linked to the following Apple Patent back in June 2010

Clearly, Apple is investing in the technology.
Unfortunately, to me, the biggest argument against the inclusion of this tech in the iPad 3 (besides no rumors or hardware leaks about it) is the argument of incremental upgrades.
The iPad is already the dominant product in the market and the only competitive strategy for the other companies has been to undercut with price (by losing functionality). The Kindle Fire is the low hanging fruit, to the higher perched Apple. Very few companies seem to be innovating in the high-end tablet market.
Apple realizes it can innovate very little from product generation to generation and still break sales records. A retina display, a faster processor, and improved cameras are all they need to do and maybe all they should do (from a profit margin standpoint).
Looking at the iPhone's hardware upgrades we have:
1) Product release - iPhone 1
2) iPhone 3g -
hardware redesign,
3g Data speeds, increased HD capacity
3) 3Gs- Faster processor, increased RAM, improved camera,
Video camera, digital compass
4) 4 -
hardware redesign, faster processor, increased RAM, improved camera, 720p video,
front camera,
retina display,
5) 4s- faster processor, increased RAM, improved camera, 1080p video,
Siri
*Major hardware additions in bold
The iPad 3 is already widely regarded to have: faster processor, increased RAM, improved camera, 1080p video,
retina display,
4g data speeds,
Siri
This is shaping up to be one of the best upgrades in Apple history. I have my doubts that haptic technology will be thrown in as well.
