MS clarified today that the free FIFA 14 for European launch countries are elegible for the Day One Edition pre-orders only. The confusion started when the official Xbox twitter account said that "Doesn't matter if it's a Day One console or not." days ago.
Graeme Boyd explained everything today in his twitter:
@brownmurder That's incorrect. Day One Editions only. I've let the team on that Twitter account know.
