I agree - 2011 going into 2012 is the rise of the semantic web
That being said, limiting yourself to one language will be equally as hurtful, as you are wearing blinders. Even if you don't know all the languages, learning why they did things (DRY, functional programming, etc) can make you a better programmer in Java or whatever language you are in. As you supplement that, you'll find overall skill increases across the board.
My personal opinion is about 1 a year will do just fine, give you enough room to learn more than a book/sample project worth, see where the language goes in a market, and give you enough time to use it for something meaingful.
Also you can switch to JPA and use any JPA provider
