Announcement Event?

Most likely, no. Unless there is a major redesign, it will be a silent update.

 

There is no "rule" on whether Apple will have an event or not. If you can wait then just keep your eye on this site and visit Apple's web site often. When new iMacs are released it will be broadly announced.

Remember this site is called Mac Rumors for a reason, rumors by definition are occasionally correct and more often not.

 

"Usually" As stated above, there isn't a formula for announcing Apple products, but a rule of thumb is that there will always be iPhone/iPad events, and MAJOR redesigns of macs.

 

Oh how I miss Mac specific events.

 

I honestly can't think of the last one, can it be the introduction to "unibody"??

 

The last one was the Macbook Air redesign at the "Back to Mac" event back in October 2010 where they also demoed Lion. But it was relatively low key as the show was at Apple's campus site.

Still, that was well over a year ago. If either the Macbook Pros, iMac, or even the Mac Pro get redesigns this year, it would be a real treat to have another show dedicated to the Mac.

 

After Tim Cook's whole "expect stuff" at the end of the iPad announcement a few days ago, i expect a redesign of the MBP, Mac Pro, and iMac to come this year most likely.

Mac Pro, obviously getting updated compenents or thrown out all together
iMac obviously getting ivy bridge as well as IMO a thinner chassis.
MBP most likely redesign

The iMac and Macbook Pro have kept their current designs for years and years now.

It's gonna have to give, and after tim cook's closing statement, i think it's most likely this year.

 

Perfect example of why this is a rumors site.

 

:d

 

What?!
iMacs were redesigned in October 2009, only two and a half years ago, when they went to 21.5 & 27" designs with all aluminum chasis and edge-to-edge glass. Technically that's not "years and years". If "years" plural can be taken to mean a minimum of 2 years, then "years and years" would mean "more than 4 years".

That being said, I could totally see a design tweak. Don't think it's needed though.
