I am sorry to hear that you find the R2 roadmap plan disappointing, because the features inside it are indeed demanded. The Material skin, the Ripple Effect, the Theme Builder and appearance customization are among the anticipated features. The new release also features a new SpeadStreamProcessing library, new functionality in RadSpreadsheet, RadGrid, RadEditor and other controls as well as the improved keyboard and WAI-ARIA support.
The reason to not include the standalone CheckboxList & RadioButtonList is that they required more time for testing and documentation to provide the quality that you our valuable customers deserve.
