Altough we have no confirmed track across the peninsula we do have received information regarding the general direction of the aircraft. If was reported to have crossed the peninsula on a southwesterly direction to then turn to a northwesterly direction
The piece of the jigsaw that I think you are missing is that at the press conference a day or so back, the Malaysian official equivocated spectacularly when asked to confirm that MH370 had in fact made the NW turn and passed through or toward the subsequent waypoints. He didn't actually deny it, but was as near as possible to doing so.
So, it appears that all that is confirmed is that the aircraft crossed the peninsular heading SW, and all the conclusions and inferences drawn from the implication of deliberate human action in turning the aircraft, except for the initial turn back toward peninsular Malaysia, are, in fact, baseless.
