Если кто подписан на Issue 2454, то сегодня должны были получить уведомление об очередном комментарии. А камент очень позитивный и очень обнадеживающий.
We're listening, we promise. This is one of the most starred issues in our whole bugtracker. Google's policy is *not* to officially pre-announce new features or give release dates, so we're not going to say anything about that.
However: keep in mind that adding another version control system isn't just a matter of throwing some stuff in /usr/local/bin and handing out ssh accounts; for both svn and hg, we had to spend a *long* time writing clean-room server implementations that ran on Google's scalable, multi-data-center infrastructure. This is one of the big things that differentiates Google Code's hosting services: we need to scale.
Осталось за малым. Дождаться :).
