Sure it's good news that companies are doing this, but who wants to spend their coins at current value. They're worth around $100 less than what they were a week ago and much more if you go further back, so a little discount isnt going to sway me at the moment.
Consumers can buy bitcoin at market value and then buy the ps4 at huge discount. This has nothing to do with hoarding and investing and hoping for higher price.
Doesn't have to be down to hoarding, but you could go buy $320 of coins and by the time you get them and try complete the purchase for the PS3 those coins are worth $300 and you're short and lost money. This is the problem for consumers but with merchants they just get the fixed price in fiat.
