From these figures taken from 3 different replication sources, we can see that Blu-ray media replication does not cost significantly more than HD DVD. In fact, we found that Blu-ray is actually cheaper per GB in many situations! It is also interesting to note that at this point, most HD DVD-ROM movies are DL, while most BD-ROM movies are SL, which would make HD DVD more expensive to replicate in most situations.
So much for the FUD spewed by HD DVD supporters.
