Redmond-based Microsoft is today launching its Office 2013 and new Office 365 subscriptions, bringing an end to the speculation of exactly when the new Office was going to land. Having taken to Twitter yesterday to tease an event in Bryant Park, NYC occurring today, a banner plastered across the Office website, which read: “Coming January 29th. More time to do the things you want,” left us in no doubt. The big launch is a significant date in the Windows maker’s calendar, especially with the Surface Pro just around the corner, it also spells the beginning of the end of the preview grace period, which will expire 60 days from now.

The packaging of any new tech product is not nearly as important as its contents, but in the spirit of the launch, there’s usually a fleeting interest in the design of the box. With Office 2013 not too far away, leaks earlier this week purported to depict the box art for those purchasing a physical copy from stores, and now, said designs have been confirmed.

The very final iterations of Microsoft’s Office 2013, along with the new Office server editions like SharePoint Server 2013, Exchange Server 2013, Lync Server 2013 are now available to TechNet and MSDN subscribers.

Microsoft has taken the opportunity to announce that the development phase of Office 2013 is complete and the engineering teams involved have signed off the Release to Manufacturing (RTM) build of the suite. Now that the coding, design and development phases of the process are complete; the main focus of the Redmond company is to now concentrate on releasing the new build of Office to consumer and business customers via selected channels.

Microsoft has a pretty busy schedule coming up over the next couple of months, and as well as Windows 8, Windows Server 2013 and the introduction of the Surface tablet, Office 2013 is also in the pipeline. The next iteration of the popular productivity suite has been available to download as a preview version for the past couple of weeks now, bringing many new features including deep cloud integration, and now the Redmond-based software extraordinaire has launched a dedicated Store for Microsoft Office 2013.

Following yesterday’s official debut of Office 2013 (and the Customer Preview, which is now available for download as we reported yesterday), Microsoft has today followed up with a post that shares more information about Office 2013’s role in the cloud as well as its future on the Windows Phone platform.

Although Microsoft didn’t stipulate an Office 2013 announcement would be arriving today, the blogosphere has been abuzz with regards to today’s announcement from the Redmond company. After a big banner showing the new Office logo was placed outside the San Fran venue, it was down to company CEO Steve Ballmer finally lifted the lid on its Office 2013.

Microsoft Office is widely renowned as the number one software package in the field of productivity, and in line with the upcoming release of Windows 8, the Redmond company is also preparing a new version of its popular suite, Microsoft Office 2013.
