ASP.NET NVC 4 is already integrated in Orchard, also is Web API, as soon as it has been released (it was ready, just waiting for the public release of MVC).
Mobile is already handled by Orchard shapes and alternates and Theme selectors, better than what MVC is proposing.
Bundling an minification is in Orchard by using the Combinator module. We've been using it on the gallery website for almost one year now.
OAuth and OpenId also has a module for that on the gallery, but I don't know exactly about the state.
