Your all looking at it wrong
PS3 has a blu-ray player built in so off course it will sell more movies (bigger install base then HD DVD players)
Once those cheap HD DVD players hit then we can really try and compare sales.
ie HD DVD could have 1000 players PS3 could have 10000 units.
If 1000 people buy transformers and 2000 out of 10000 people buy some blu-ray movie it will still appear as blu-ray is selling better.
