Whishes...
I think, wish, expect the WWDC to be focused around software. Snow Leopard, Final Cut, Aperture, iPhone OS. These should be the focus. It has been a long time since Apple really put the "pro" segment under the spotlight. MacPro deserves/needs a desing upgrade (also to "match" it with the new screens), pro apps need a refresh (FCP and Aperture particularly).
I wish WWDC had these in focus and not "iPhone" all the time... From a SW point of view of course, but presenting new "consumer" hardware at WWDC is not quite appropriate. But then again Apple has to do it there, because all the "analysts" will be expecting it and the stock would tank, also because of the release of Palm Pre which put more pressure on iPhone (FROM A MEDIA COVERAGE POINT OF VIEW)
But I hope it will only be PART of WWDC and not the WHOLE WWDC...
For the "tablet" or the new "appletv" or every other consumer announcement, there will be the subsequent announcement made by Jobs himself.
I also wish AppleTV would get an upgrade (with an appStore for games, small at the beginning but very strong in time).
Most of all I also wish, at the announcement of iPhone's ability to download TV shows and movies, as well as a possible new AppleTV that the person on stage adds the magical words it's been 3 years I would like to hear... "WORLDWIDE".
I would like a Pro centered and software oriented WWDC (with announcements of the 3.0 iPhone, new Aperture, new FCP, new ATV OS, Snow Leopard): after all there would be plenty of stuff to talk about.
And then, a month from now, a consumer event with the announcement, by Jobs and Ive, of a new device or two (tablet, iPhone, ATV, new MacMini, you name it): there also would be plenty of stuff to talk about...
Regarding Steve's health. Since he left there has been speculation, expectation and even pressure for him to take the stage. I bet, when he said "until june" he had to be strict and avoid temptation to appear prior to that (also because he is very passionate about Apple, a thing that an analyst or two sometimes forget).
I am happy Steve will be back, and I hope he will be full of energy, vision, idea and focus. But Apple really needs to remember it is not only a consumer company, but also has some really strong assets in the business world which they shouldn't forget. Unibody laser etched or whatever tech they use for a MB which is consumer oriented is fine, but I would carve the MacPro in pure gold then, for the price people pay for it... (a MacPro never sits on the floor and is always really visible. It needs a design refresh)
