Paramount has released some pre-Nielsen figures for sales of their highly anticipated Transformers HD DVD release.

In it's first week, the HD DVD version sold 190,000 copies, the most ever for a single high definition format. I say single, because Warner's 300 still holds the record, with Blu Ray and HD DVD combined sales at 250,000 in it's first week. The Blu Ray version of 300 sold approximately 165,000 copies it's first week. Of the 190,000 Transformers HD DVDs sold last week, over 100,000 were sold on the first day of sales. It's good news for both Paramount and the HD DVD format, which is still fighting an uphill battle against rival Blu Ray despite a run of good sales weeks since Paramount announced HD DVD exclusivity in August.

To keep things in perspective, the DVD version of Transformers sold 8.3 million copies in the same week.
