Above is a copy of the D&D Starter Set, which is going to be the first release of the new D&D line, followed by a Players Handbook, Monster Manual, and DM Guide, each a month or two apart. I haven't been keeping up with the playtest versions of the rules, so I don't really have any opinions on the new edition other than the artwork. Which so far I like. They appear to have ceded the crisp, Vallejo-like detail to Pathfinder, and gone with a more raw look.
One of the real outstanding issues is what the third-party publisher agreement (if there even is one) will look like. I think that's going to shape the success of this edition a great deal.
