Does anyone have an idea when MS will be putting these much needed updates into play?

New features for Microsoft Outlook Web App in Office 365

In particular the Enhanced Document Collaboration.

Outlook Web App now includes full integration with OneDrive for Business, allowing users to easily share files stored in the cloud as attachments in e-mail. Files can either be automatically uploaded from computers to the OneDrive cloud drive and sent as a link in the body of the e-mail, or sent directly from the cloud drive as an e-mail attachment.
