Amazingly, there seems to be no 4E content out there except for scanned copies of Races and Classes. (And no, I'm not going to share my research methodology on this one with you.) However, there are ways to discourage scanning and distribution for a small print-run (like playtest documents) that are not economically feasible for a larger print-run. Additionally, there are social and psychological incentives for those within playtests to maintain confidentiality.
4E may be one of the last big RPG projects done by a company the size of WotC. Electronic distribution is just too easy and it is too easy to overcome controls on that distribution. If the US moves to a new model for artist compensation, then WotC may not be able to gain the revenue from copyright in the same way that they did in the past. Now they may be able to thrive under a new system, but I suspect that fan-based projects done over the internet will fare far better under any alternative economic scheme for rewarding artist contribution.
