Not all peoples act the same way when there face contradictory informations. But the point is not to react to the individual view in a such situation, because there will be very different behaviors. It's a fact on how the human brain work at the individual scale. Some will talk about official statement, some talk about current product release, some talk about there hope, etc... The point is to realize that there is currently different possible interpretation of the available informations. And this will continue this way until there will be a more coherent set of information, that will assert some previous info and withdraw some others previous info.

Very simply put, the problem is:
* Nokia officially say his future is WP only.
* Nokia officially release a brand new Meego N9.
* Lot of reactions external to Nokia acclaim the Meego N9 and challenge the WP only future decision.

Now there is two basic directions:
1) Continue WP only. Nokia value will fall because it kill it own Meego value (and actually the only one that is publicly acclaimed for that matter, as WP is just WP as already do Samsung or HTC).
2) Continue Meego. Nokia value will fall because of the hug loss in effort in a pointless WP development.

Clearly Nokia need something more subtle to expect a rise of his value. But what ? This is the question for me.
