The first beta of Edge is pretty basic as it supports not much beyond animations of HTML and SVG content. Adobe will expand the features of Edge over time and will release the full version sometime in 2012. Adobe doesn't feel as if Edge, and by extension, HTML5, will challenge Flash in the short term and sees the two as coexisting. Flash is better suited to games, streaming media, and data-driven visualizations, while HTML5 is better suited to interactive Web pages and advertising. The beta of Edge is concentrating on those two categories, and although Edge supports the latest version of all current desktop and mobile browsers, older versions of those browsers aren't supported at the present time. Adobe may add support for older browsers over time, but that will depend on what the developers using Edge want. Hopefully Adobe will be able to create more programs like Edge in case the transistion from Flash to HTML5 sees Flash die off completely, since the death of Flash will adversely affect Adobe.
