I was involved with the Microsoft Access 2010 first non-public beta. A non-disclosure agreement prevented me from discussing details but now there is a public version available. This should not be placed on a production machine and also not on a machine having earlier versions of Access you need to use. This version has the ability to publish an Access application to the web using ?Sharepoint Access Services?. I have heard from various sources that any time from March to June 2010 will be the first release.
DailyAccessTips.com has a list of Access 2010 feature demos.
