>>Also Blu-Ray movies are not necessarily released at the same time as their DVD versions.<<
I’ve had my PS3 for months and I have NEVER seen a delay in Blu-Ray.
I went to a local Meijier for Iron Man at 3am. They hadn’t put out the Blu-Ray. Down the street to Walmart and it was there.
No problem.
The big, featured release of the week is probably going to have both available... but there are usually between 20 and 30 other DVDs released that do not have a Blu-Ray version released (either it's not planned or it's delayed) in the same week.
