Ask HN: Do the big tech companies know their competitors' plans?

It seems unlikely to me that a major tech company could manage to keep development of its new products secret from its competitors, for the following reasons:

- The stakes are extremely high; knowing your competitor's plans early can make or break a business.

- The major tech companies are constantly hiring employees away from each other, resulting in plenty of employees who know about the competitor's most recent plans.

This kind of activity may be illegal, but there's no shortage of examples of corporations getting away with bending or surreptitiously breaking the rules.

So: Does Steve Jobs know Google's product roadmap? Does Eric Schmidt know what the next iPhone will look like? (And so on.)
