Well, point for point:
'Price': There'll be a sub-$500 Blu-ray player out in the US by the end of the year, in all likelihood.
'Industry support': There's no evidence to support their claim. Blu-ray currently enjoys significantly stronger support from Hollywood studios than HD-DVD. Sony and MGM won't go anywhere, and Fox is almost more bullish on Blu-ray and its success than Sony itself. My only question mark would be Disney..
'Beta-rays own difficulties': They were the same difficulties HD-DVD were facing, which prompted interim AACS licensing. PS3 delay != Blu-ray delay. Blu-ray is launching in May. 50GB movies will be out in the summer.
It's rather shoddy FUD, nothing more. The whole "beta-ray" references make it read like a bitter TeamXbox post or something.
