The next Office Suit Office 2010 (including Office Web applications, SharePoint Server 2010, Visio 2010 and Project 2010) will enter a technical preview in the third quarter of 2009 and will release to manufacturing in the first half of 2010. SharePoint 2010 will be 64-bit only. So Sql server 2008/2005 64 bit is supported with SharePoint 2010. Also Supported operating system is 64-bit Windows Server 2008 or 64-bit Windows Server 2008 R2.
The main focus on this next office suit is like "Office everywhere". So it just like office application on web. The line between home and work has blurred, so people want more choice and flexibility in how, where and when they work. They’re also demanding the ability to access and effectively manage their information whether at home, at work or on the go. With next office suit familiar interface will be provided across pcs, browser and cell phone. Microsoft has got that people want the freedom to use office applications from more locations (home, office and everywhere) and on more devices.
Though Office 2007 integrated with web but Office 2010 may be the true web base office system. So is Microsoft moving from "Microsoft office" to "Microsoft Office on Web"!!!!!!!
