I agree, we won't see what's happening with BR and HDDVD for another 2-3 years TBH.

The good thing is that the PS3 potentially is strong enough to last at least 7 years and could be around as an incentive for buyers (as long as BR becomes the no.1 choice). 

So what do you say about the assumptions that BR-players might become cheaper as a stand alone then as a PS3?
