Personally I'll be waiting till after the closing arguments to make a personal decision as to what I think OP is guilty of with regards to what happened on the evening of the 14th February.
I've only just started reading the transcripts of the prosecution case prior to Pistorius taking the stand and there's still a hell of a lot of the defence case to be put. I don't think anybody should reach a judgement until all the facts are weighed and the arguments finalised.
That said I'd be surprised if he wasn't found guilty of the charges relating to the restaurant. Then again the defence is far from finished.
From what I've seen I don't think the prosecution has made a strong enough case (so far) for him to be found guilty (beyond reasonable doubt) of having premeditated the murder of Reeva Steenkamp specifically. However the way the case has been tried before court and witnessing the prosecutor's style in cross examination means that an extrapolation of the prosecutions final arguments is difficult. Nel seems to take a piecemeal approach to questioning, whereby things are put on record in a fairly haphazard fashion - out of order of their happening.
If we relate this, for example, to his questioning of Pistorius I suspect that he may have found enough inconsistencies, logical contradictions and admissions to at least put Pistorius in grave danger of being found guilty of culpable homicide and possibly even murder even if it is granted that the greater part of Pistorius' testimony is true. Again it depends on how well the prosecution weaves these miriad inconsistencies into a cogent closing argument and how well the defence can explain them in a different fashion.
We just have to wait and see.
