When will Professor Layton games be localized?

I'm wondering if Professor Layton and the Specter's Flute will ever be localized to North America. Or, if there is a english rom that was released. But I don't think that there are Japanese to English versions of Professor Layton. Also, will Professor Layton and the Mask of Miracle also be localized to NA? It's been a while since a Professor Layton game came out.
