After using Raudus for a few months I decided to post my own answer.
The framework is improving, Sencha touch support now it is not complete but sufficient to create usable web applications optimized for mobile devices.
RFE, a new front end, not based on Sencha Touch is under developement and in next Raudus release (that should be out soon) there will be a usable preview of the new controls set.
So while ExtPascal seems frozen, Raudus is in progress and promising.
Update: I stopped using Raudus, it dropped ExtJs support and now it ships with own controls, that will never match the beauty and richness of extjs components. I am now going for IW + cgdevtools components that are Jquery UI for IW.
