WoTC Creates D&D Basic Rules Website

Recently, Wizards of the Coast quietly launched a hypertext version of the Player's Basic Rules for the latest edition of Dungeons & Dragons. While it looks somewhat austere, it is definitely functional and easy to navigate. Considering Wizards hasn't had the best web interfaces before, they definitely earn some points in this regard. Hopefully,  we'll see a DM version of this in the near future.

However, the appearance of this site does raise a simple question: why haven't they updated the PDFs? While the PDFs are functional, they are still missing some very basic elements like a table of contents or an index. Heck, it would be nice to see some of the more basic rules and advice from the Dungeon Master's Guide included in the DM PDF. However, it's been awhile since they've made any notable changes to either PDF. Part of me wonders if this website might be the replacement for those documents and a glimpse at the upcoming SRD for the new license. With that being said, this is just speculation, so take it with a grain of salt. 

What do you think? Are you glad to see this website? Would you like to see a website for the DM's rules? Why do you think they haven't updated the PDFs recently? Do you think I might be on to something with my speculation, or am I completely off base? Leave your thoughts in the comments down below.
