This is what the PS3 can do at best. Q4 2011 it's only € 100. It's unlikely to sell the PS3 for 5 years at the same price. They might choose to stretch the price cuts or make them smaller. Either way sales will be lower within 5 years if they do.
However the PS3 is huge competition for standalone Blu-ray players. We will have to wait a few more years before Blu-ray attracts mass market appeal 2009/2010. Up until then Blu-ray isn't important for PS3. Up until now Blu-ray has only hurt the PS3. This doesn't mean the PS3 is superior to the Wii. Without Blu-ray the PS3 would still loose against the Wii. Blu-ray is just a non-gaming aspect that could drive sales extremely well.
