There are several HTML5 inputs not on this list, and at some point they will make an appearance, but for now I think as a starting point these are probably the most useful ones.

I am also not convinced some of the HTML5 inputs such as the datetime and datetime-local are even a good idea.They have pretty brutal usability issues and can probably be better accomplished through the use of multiple inputs.

Checkboxes

The focus with checkboxes will be to make them easier to work with. Styling and positioning the standard form element consistently across browsers can be quite painful.
