Top Google execs like Andy Rubin were expected at the event. AP Samsung and Google canceled their big Android next week out of respect for Steve Jobs, a source close to the two companies tells us.

Earlier this morning, the two companies issued a joint statement saying "both parties have agreed that this is not the appropriate time for the announcement of a new product."

According to our source, it's not the "appropriate time" because of Steve Jobs' death Wednesday night.

We were also told the event's cancelation is not related to delays in the product the two companies plan to announce.

(That product, by the way, is expected to be Samsung's Nexus Prime running Android Ice Cream Sandwich.)

No word yet on when the event will take place.

UPDATE: We just got confirmation from a Google spokesperson:

We believe this is not the right time to announce a new product as the world expresses tribute to Steve Jobs's passing.
