There is a website which maintain a voting system about which language has been used in 2013. The presentation is very nice.
Of course, you should vote for your favourite language (I hope it is Delphi).
To vote you need a Tweeter account. Send a tweet using the hashtag #code2013 and then the language you vote for.
You can see the result, updated every 10 minutes at http://code2013.herokuapp.com/
