...I guess I just don't buy the notion that "This is the best they can do," and that the consumer is just supposed to smile and take it. It's not so much about the disc change thing, it's about what are we actually getting for our money, and I see a large swath of the market that simply does not give a rat's ass about it and is happy to plunk down cash -- repeatedly -- for the same stuff with incremental improvements every, oh, 2-3 years...
Ah, but that's the beauty of consumerism - I can choose where and when to spend my dollars. I love the fact that companies throw multiple options at me - let me pick and choose which version, how much I want to spend, etc. Love love love having choices.
Regarding the "incremental improvement" - there is a vast upgrade from DVD to Blu-Ray, although as with anything, there will be exceptions. Some films did not take the transfer from DVD to Blu-Ray well, and these can very often be found by doing some research before purchasing. However, the vast majority we've watched have shown significant improvements over DVD.
I'm a huge LOTR fan and, as such, will have no trouble picking up the EE's when they come out this summer, to go along with the Theatrical Blu-Ray's we bought last year. Each version has it's place in our house, and we will watch each accordingly. We also sometimes have films on Blu-Ray and DVD, as our downstairs TV (which we use while exercising and my wife uses while crafting) is DVD-only, and utilize the PS3 for Blu-Ray upstairs. When they started releasing the combo packs that had both Blu-Ray and DVD in the same package, I was a very happy boy. :thumbsup
And as for the 2-3 years, I find it's much closer to 5-7. We finally picked up the EE DVD's for LOTR in 06, and now the EE Blu-Ray's in 2011. At a total cost of roughly $70 for 5 years of viewing before upgrading to Blu-Ray, I'm fine with that. Works out to about $14 per year for the three films, and as often as we've watched them, I know we've gotten our money's worth. The Blu-Ray's will end up being no different.
