I don't know where the '26% experience issues with html5' figure comes from. Based on the colors it accounts for IE<9, but the numbers show 19%+5%+4% for IE<9 (which does not == 26%), of which many HTML5 features can either degrade nicely or be polyfilled, at least for IE8, so you could argue about inclusion of that 19%. Also, define 'wealth of capabilities', opposed to 'does not currently have some Flash features', as the reverse can also be said just as easily. As for 3D, WebGL looks capable enough to me (but that may be because I already know OpenGL)
