With all due respect to Paul Masson, it looks like Microsoft is not going to sell sour wine for the sake of hitting dates. Although I, among many others, are chomping at the bit to get our hands on the RTM (final bits), it looks like we are going to have to wait a little bit longer. The current launch date for Visual Studio 2010 is March 22, 2010 and is schedule to coincide with the DevConnection conference in Las Vegas. I would suspect Microsoft will continue to hold that launch date unchanged but will simply delay the shipping date.
Somasegar announced yesterday afternoon that Microsoft is not convinced that the BETA 2 of Visual Studio 2010 is fully baked. He sites some performance issues that he feels can be improved and that slipping the RTM date back a "couple weeks" is going to be worth it to developers over the long run. Scott Guthrie also made a similar announcement.
With this delay, Microsoft has announced that they will be releasing an interim build (an RC release) in February to give developers a preview of those new performance enhancements--as well as one final chance for developers to provide their feedback prior to RTM. On a positive note, Scott assures developers that the new MVC 2 RC (instead of MVC 2 Preview 2) will be fully baked into this RC release.
Both Somasegar and Scott also announce that this RC release will include Go-Live licenses. This means that Microsoft will be supporting this release in a production environment and that it considers this release to be rock solid.
Microsoft made a number of announcements at or around PDC this year including some big ones relating to Microsoft Office and Microsoft SharePoint 2010. As you may already know, the “Office” has been removed from SharePoint’s official title; which is now simply Microsoft SharePoint Server 2010. This means the MOSS acronym doesn’t work anymore. But don’t start using MSS since that acronym is used by Microsoft Search Server. SharePoint is just SharePoint.
SharePoint 2010 BETA is now available and can be downloaded here. Many of the developer tools in SharePoint have been greatly enhanced to promote increase productivity. A formal list of benefits can be found here or another good list is on Arpan Shah's blog.
What started out as a leak was later confirmed by Microsoft; the official RTM month for Microsoft Office 2010 is next June. One can only extrapolate that with the tight integration between Microsoft Office and Microsoft SharePoint that both will release at roughly the same time.
So... if you are someone that has Office 2003 should you wait until June to upgrade? Microsoft doesn't think so and is offering some enticing promotions to get you to upgrade sooner rather than later.
Or, if you're like me, you download the BETA and just use that
