At the moment it only has the high level public items we are working on for the next 30 days (and a lot of low level details which are not yet published). However, later this week we are going to expand include all the cool long-term features that we are working on, such as Clan Warfare, Asylum, Racing etc. which really will open the game up to a whole new set of experiences.
Instead of answering the same questions (and quite frankly - zany conspiracy theories) over and over again on forums and on the blogs, we figured we'd rather publish all the ongoing work in one place, so if you have any concerns or constructive suggestions, hopefully the most common issues (lag, queues etc.) are addressed as ToDo items in the Road Map; for example the upcoming Firewall rebuild happening this week in the EU, the new ISP peer and IP provider we are adding next week to improve latency for EU players, the launch of the CBAK (Closed Beta Appreciation Kit), the launch of car kits, the new matchmaking and the new district recommendation items.
So - while the current list is just a taste of what we are hoping to share, at minimum our aspiration is to NOT promise things "soon" Wow-style, nor on "Valve-time" but instead the plan is simply to share things that we feel comfortable promising within some reasonable time frame. Will we ever miss a date? You'becha. And occasionally we will beat a date or two by getting there a tad early. But the general development direction should certainly be very clear from the roadmap itself.
