I am not surprised at all the speculation going on here - this is clearly a very unusual accident and the eventual explanation will be of a very unusual and rare nature. One would not have expected that the pilots of AF447 would display such levels of inability to fly their aircraft and would crash it in such a way.
However, it would be wise to wait until at least a little more information emerges. One should also not expect British or American levels of transparency from the Malaysian authorities. Other countries organisations don't necessarily share the view that all items of information should be released and so withhold certain items. They also get very prickly when challenged (bureaucrats are like that). Military involvement will also limit the amount of information released. Military organisations are past masters at operating the 'need to know' principle to its fullest. Add in possible turf wars and one begins to think that it is amazing that so much has been released. All this, though, doesn't help the search which would benefit from sharing information. But then a search involving a lot of different agencies always has the flavour of trying to herd cats.
