At the end of last month, Samsung sent out invitations for a big mobile event called Unpacked 2011, subtitled “The Google Episode.” The invitation asked for invitees to join them to “get a look at what’s new from Android.”

The event was supposed to kick off this upcoming Tuesday, October 11th in San Diego.

It’s been widely speculated that the Unpacked event would be the place where the new Google phone, the Nexus Prime (or Galaxy Nexus), would be unveiled. Another draw for the event was the probable showcasing of the latest Android OS, Ice Cream Sandwich.

You might have noticed that I’m speaking in the conditional and past tenses, and that’s because it looks like we won’t be seeing a big product launch on October 11th.

Samsung and Google released this joint statement this morning:

Samsung and Google decide to postpone the new product announcement at CTIA Fall. We agree that it is just not the right time to announce a new product. New date and venue will be shortly announced.

So it looks like we will have to wait for that official Nexus Prime reveal.

Why would they feel like it’s not the right time to announce a product? The 11th is exactly a week after Apple’s big October 4th iPhone 4S launch. It seems like a perfect time for Google and Samsung to strike with a brand new phone. Samsung has went to the trouble of producing trailers for the big event that say “something big is coming.”

Could it be Steve Jobs’ death that has led them to this decision? Whatever the cause, Android users will wait anxiously for the rescheduling announcement.
