I really doubt Apple would do a hardware refresh with CeBIT going on soaking up the attention of the gadget world. Not sure if they would roll out a new release between CeBIT and iPAD release. We might be looking into April for updates..
Unfortunately, I think Apple might have some big updates planned for the Macs. I wouldn't be shocked if the MBP gets a silent update between now and early April and the MBA, Mac mini, Mac Pro, AppleTV, Cinema Displays, and iLife all get updated at WWDC in June.
I just don't know if Apple can hold out on the MBPs until June... a full year is absolutely ridiculous in my opinion, but Apple marches to the beat of its own drum. I just don't know... I think with the long wait, we could be looking at some new designs even. So maybe not June but maybe a day between April 12 through 29th, Apple has its own press conference for Mac updates. I just think with the WWDC being six weeks (approximately) later, Apple might opt for a full year between updates.
I was convinced that March 2, 2010 was definitely the day... but I have been waiting since October 2009 for a REAL UPDATE for the MBA. With the mediocre teeny tiny spec bump for the MBA last June, I figured Apple had plans. Everyone has been expecting an MBP for three months, so Apple has to do something there. It's now at 9+ months when the MBP usually gets at least a spec bump on a seven month average cycle.
The iPad must be changing the game... along with the loss of Nvidia's GPU/chipset from all Macs. Or perhaps, Apple is waiting on 10.6.3, or a part of some sort. It just seems like disappointing updates the last time had to lead to quicker and much more relevant updates, but that was NOT the case.
I do plan for complete disappointment. If Apple fails, which is highly likely, the Sony Z really could be my future computer. Apple cannot release an MBA with Intel's graphics as the sole graphics non-solution. It cannot release an Ultra Low Voltage CPU. It cannot release only 2 GB of RAM, and it must at least keep a 13" display and full sized keyboard for me to keep the MBA my primary Mac. I bought the "fake rev C" last Summer thinking it would be my computer for just six months until the real update was announced... it has really led to disappointment with its lousy 2 GB of RAM, and without a CPU or graphics system update. I welcomed the price drop then, but right now I just plain don't care what the price is, I want a new relevant MBA.
Come on Apple, if you cannot deliver, a shiny new Sony Vaio Z surely can! With a Core i5 CPU, Nvidia 330 GT, 4 GB RAM, dual SSDs (256 GB total), and Windows 7 driving the hardware I can get really excited if I have to make the switch. Apple needs to deliver now more than ever. Sure I would prefer an MBA, but I will not wait forever and I will not be happy with an MBA that's meant to be a secondary Mac.
