Yes, he was in the past confirmed. However, http://io9.com/5543025/supernaturals-showrunner-sera-gamble-talks-about-god-and-endings. Now, most likely as the series has continues well for two complete for two seasons.. (As season 8 despite being finished filming hasn't been aired completely so it's not complete yet.)

But, back to point regardless if Chuck has God is taken back as canon, I think it's kind of odd, mainly how it ended in season 5. Now, this is my theory on an attempt on if THE SERIES, do take it back. As Chuck is a in series avatar for Eric Kriple, him vanishing at the end of season 5. Could be like a teaser about, how he Eric was leaving the show. And another reason could be, as this was Sera and Jeremy etc and any future showrunners. Might want to do more with God or Angels. Like with Metatron, the Words of God, and Naomi etc. Again, I am not stating for 100% accurate sure tha Chuck is God it's like 95% in my opinion. But, as Sera whom wasn't even the showrunner, but one of the main writers would know if Chuck was God. Another, short theory. Chuck was really a prophet, but then died, or God took his place and appearance. So, if they do decide to truly put God in the season. They might use Rob or another actor.

Also, I know that Jus In Bello Italy 2011, Rob confirmed that Chuck is in fact God. He explains that other members of the cast, as well as Eric Kripke himself had asked him how it felt to play God.

BUT, Rob was kind of criptic as some think he meet, Chuck as the Prophet writer of the series in the series, as Eric uses the metaphor Writer as Creator. Also, if it was 100% sure, than why or how can fans have officially speculated the Chuck was Metatron for early parts of season 8?
