The Blu-ray momentum is still very young. To see its full effect, we need to wait for one or two more years.
Blu-ray will cease to be a factor in the console war in two years. The PS2's DVD playback was a temporary advantage that evaporated after two years, and the same will be true of Blu-ray (assuming the format doesn't tank). Regardless of what price cuts occur to the PS3, standalone players will be available for half its price 2 years from now. The PS3's Blu-ray advantage is now, not later.
