I predict Microsoft releases a new Office version for Mac 2015 only because I like the new leadership of the company and they aren't making bonehead moves (yet). They need to be a software company again - sure make hardware products but don't neglect the software. Word for Windows is far better than Word for Mac. The longer they wait to release a new product the more people jump aboard the hate wagon for Office.
Microsoft is definitely releasing Office for Mac. Sooner or later it will release. Microsoft is already late and there are no signs of the new Office. Not even a beta version. But it will eventually come out.
Personally I'm just about there, if a new Office doesn't arrive soon, I hope to never use it again. For those who say they "need" office.. you only really need 2011 for select files and select people. Many other programs are available nowadays. Whether or not you want to use those programs or want to be a stickler for Office is another discussion entirely.
I both need and want Office. Yes, there are alternatives available, but it's not the same thing. Some people may find iWork or LibreOffice as replacements for Microsoft Office. But they are poor replacements.
I need Office because I work in a corporate environment. Not having Office is not an option. Everybody uses Office and expects me to use Office. I could use an alternative, but there would be the risk of minor incompatibilities. And these inconsistencies are usually not tolerated in a corporate environment.
What if I save a draft contract in LibreOffice and then somebody else has to open it to print and sign and the cross-references are missing? What if I produce a presentation in Keynote and then I have to open it in someone else's computer to give a talk before a large an audience and then the file does not open as expected?
No, I cannot run the risk. I have to use Office. If Office for Mac is not good enough, then I have to turn to Windows so I can use it, because it is what everybody does and I cannot afford to be different.
And you know what? Last week, the IT department of my firm came with a budget to migrate to Office 365. It was not cheap, and I asked for alternatives. The guy laughed at me, like he said: "Are you insane?" or "This is just ridiculous". And I have to agree. Office is a must-have. iWork is a joke, a very bad joke, made for children's homework. And LibreOffice is nothing but an illusion to which open source enthusiasts keep alive so they can dream of a proprietary-free world of software.
But I also want Microsoft Office. Microsoft Office makes my life much easier. It has more features than other programs, and I have the piece of mind of not having to convert files into other formats.
So, yes, I both need and want Microsoft Office, and if Microsoft does not release a new version for Mac, I may end up turning back to Windows. Nothing on the Mac, at least for me, could justify the absence of Microsoft Office, which is perhaps the only killer app on the desktop right now.
