I don't the announcement delay would lead to release (into shops) delay. So it's not about them being competing products, but about getting maximum media bang and attention.. Even so, I think not announcing at Nokia World would be a mistake. Right now Nokia needs a full on, full side, onslaught of an announcement from the low end (S40 TS) to top end (N9) and in between (services, C7, X7, E Series) to show that they are back in town and that their strategy is on track.
