$30+ for New Release Blu-Ray vs. $20 or less for DVD is somewhat expensive. I don't really give a crap if I can see "500 Days of Summer" in 1080p....definitely not worth a 33% markup.....I reserve my bluray purchases for over the top visual and audio flicks (ie Transformers, Star Trek, etc.)
I reserve my Blu-ray purchases to movies actually worth owning. And if I'm going to own it, I'll be darned if I'm going to waste money on SDTV.
I have about 100 discs, with an average cost of under $15 a title and I started buying the day the PS3 was released.
From day one Blu-ray has had fair prices on titles for those who cared enough to look. What I do find suprising is how many people that don't buy the discs who are the most vocal about complaining about the price. Ex-HD DVD supporters should be especially ashamed if they bring it up since, on average, Blu-ray was always less expensive to purchase discs for to consumers.
There are years to go on all of this. HDTV has 50% market penetration in the USA despite a complete lack of anything but HDTVs in stores. Half the country still enjoys their old tube televisions. We have at least half a decade to go, if ever, before BD will even be viable to replace DVD.
Frankly - I don't care if it replaces it as long as we see title after title released on the format then my personal enjoyment is fullfilled for HD movies.
