We can't say we're too surprised about this development, given the Team Fortress 2 team's love of Minecraft. Notch, according to a tweet this morning, is in talks with Valve over the future of Minecraft. As he has expressed desire to bring the excellent construction and survival simulation to Steam, that seems like the obvious choice, but other possible outcomes include licensing the Source engine for a future game or even being absorbed into Valve proper. It's also completely possible that none of these are happening, and Valve simply wanted to talk with Notch because they are huge fans of his work. This association is great news for both Minecraft and Notch, as interaction with Valve will give the Swedish developer even more exposure for his incredible independent title.
