Well... in my opinion... YES, he is gonna be there!
why? you ask me?
let's put it this way...
1. there's a 99% possibility that the new iPhone will be announced that day. (to start shipping mid-july)
2. there's a 90% possibility that the iPhone OS 3.0 will be fully released that day too!
3. there's a 80% possibility that Mac OS X 10.7 "Snow Leopard" will also be announced that day. (and start shipping either the same day or a bit later on in the summer)
4. there's a 70% possibility that the much-talked-about touch screen "Netbook" will also be announced that very same day...
AND he said he'll be off duty until the "end" of june and WWDC is either Mid-June or early June... so a week or two ahead of his planned return won't hurt him...
IF Steve returns that day with a "1, 2, 3, 4" presentation for the iPhone, iPhone OS 3.0, Snow Leopard, and NetBook... shares will soar upwards! Media will go crazy! and us? even Crazier! 😀
Let's just hope he will get better! We miss his keynotes!
