I just talked to Tim Cook and he revealed to me the following features for iPad 3:
- LTE/4G capability;
- Retina display;
- 32/64/128GB options;
- tactile feedback surface/virtual home button;
- Thunderbolt port;
- Optimized dual-core processor, leading edge GPU.
Mark my words and see for yourself on the 7th...
Obviously this is a joke, but a Thunderbolt port? Really? What percentage of iPad users are going to use Thunderbolt devices with their iPad, 0.005%? I don't think apple is adding cost, hassle, etc. to please the 1 in 20,000 users who would use such a port.
Sure, on this site many people are techies and fan boys so queue the "I have TB devices and would love this" comments but your parents, grandparents, school children, and non-techie adults (about 80% of the iPad buyers) never heard of thunderbolt, much less own devices for it, and even much less would see the need to hook those devices up to an iPad.
LTE/4G is probable with all the rumors swirling around, retina display is a given. The storage depends on the cost, but its not TOO far fetched that a 128GB option may arrive (even if the 16GB is not pushed out).
The GPU/CPU is a no brainer, I have no doubt we're going to see improvements there and with the graphics (due to the retina display being more hungry for power).
Tactile feedback. Id love to see some ideas on how this would work. But some sort of localized vibration or something could be interesting. I guess we'll have to wait to find out!
Whatever Apple does its sure to blow competitors away for at least another year, because even though Android tablets come out every month it seems, Apple is going to be on the shelf for 12 months so they have to make sure they are so far ahead that they can wait 12 more months for the iPad 4.
