No Minecraft snapshot for several weeks, possibly a 1.5.2 update in April

Minecraft 1.5.1 has been out for a few days now, and it looks like the Mojang office is calming down with updates for a bit. Replying to a person on Twitter, lead Minecraft developer Jens said, "To answer [his] question, we don't plan to do snapshots for a few weeks. However, the Realms team has requested a 1.5.2 in April." If you are unaware, Realms is a new feature currently in closed beta testing that allow you to create Mojang-hosted servers.
