$ony BD, meh!
Looking at Play.com, taking the first title that come into my head:
Hellboy (2 Discs) DVD £2.99
Hellboy (Blu-ray) £13.99
Verbatim DVD-R 16x 50pk Spindle £11.47 (for 250Gb backup)
Verbatim 10 Pack 4X Blu-Ray-R 25GB £69.31 (for 100Gb backup)
You can allow for early adaptors, cost of ramping up production and so forth all you want, but at the end of the day, the average shopper, looking at the price difference in Asda will take one look and think:
"How much? But it's the same film!? You're taking the piss mate!
Besides, I personally don't believe Blu-ray should have won out. Notwithstanding all the testosterone based arguments between the CEO's during the 'format wars' HD-DVD lost for one stupid reason - it didn't get put in to XBox at the start.
I know for a fact that companies like NEC were in negotiatiins with MS, so I assume the reason came down to cost, the manufacturer(s) and Microsoft arguing over pennies in a £300 unit. Bloody daft if you ask me. If a punter is going to buy it, £299 vs £349 for a much better, more functional unit is not going to be a massive issue.
At the end of the day, as we all know, without PS3, there is no Blu-ray market, hmmm.
Stick me in the NOT using Blu-ray column.
