Microsoft has already said it hopes to deliver the final version of Office 2010 in the first half of next year, but the folks over at Neowin apparently have it on good authority that the software giant is right on track for a June launch. As many as six different flavors will be offered to customers, including the limited-functionality Starter edition, which will feature free, ad-supported versions of Word and Excel.

Microsoft's latest productivity suite will also be offered in Home and Student, Home and Business, Standard, Professional and Professional Plus editions. No official pricing for the full or upgrade versions of Office 2010 has been announced yet. Additionally the company will make Office Web freely available to anyone with a Live account, and plans to launch Office 2010 for Mac OS X sometime next year.

In the meantime, Windows users can get a glimpse at the suite's newest features by downloading the Microsoft Office 2010 Professional Plus beta here.
