I would have to totally disagree with that as the push for the use of HTML 5 is to move to everything running within a browser.
Web Wiz Forums already comes with a mobile interface for using in Mobile Browsers. Creating a mobile app would be like recreating the wheel and as mobile browsers get more advanced further features will be added to the mobile interface of Web Wiz Forums.
However, development work will not be diverted to work on a mobile app for Web Wiz Forums, given the work already in place for the Mobile Browser interface.
