New language this year

There has been discussions going on the pragprog about which languages will you learn in new year, some mentioned the languages that I never heard about. I think I'll learn ruby or groovy and C# 3.0. I've heard that C#3.0 has some cool features which deserves attention. Ruby seems to be hyped too much these days, not that its bad, but it certainly is being re-branded like no other language ever! Ruby is around since many years, but the Rails put it in the news, anyway, I tried ruby online and i found it cool, it has lot of utility classes which can be quite productive.
