Google switched to a new translation system for the remaining language pairs on the Google Translator which were so far provided by Systran. The translator help files don't mention this yet, but it might be possible that the new translations are the results of Google's in-house machine translation efforts.

Google switched the translation system from Systran to its own machine translation system for all the 25 language pairs available on the site. Until now, Google used its own system only for Arabic, Chinese, and Russian.
