[quote name='sparklecopy']As long as you get the content at a reasonable price I don't need to worry if sony will fail. Minidiscs lasted for 15 years even though no one bought them in the states.[/QUOTE]
Minidiscs were crippled at the consumer level (which hampered, nay killed, their adoption), but you're right... platform agnosticism is definitely needed in this generation. Because with a clear winner and loser, we as gamers lose big time. I'm not going to pick a PS3 game over a 360 game simply because I want to support the PS3, and vice-versa. Competition means we all win with better games, fewer platform-specific exclusives, and more bang for our buck.
As for HDDVD v. Blu Ray... well, I believe the same thing holds true... competition means better products. However, combo discs might be hampering HDDVDs a bit more than Blu Ray. $35 for a combo disc (even with extra features) is a bit steep, even if you get both DVD and HD versions. People who only have a DVD player now aren't going to bother "buying for the future" for the most part, because it's not cost effective to do so, when the DVD only version of the movie is $20 on sale for $18 in the first week. Asking them to future proof (which they wouldn't necessarily have to to begin with) their collection for almost twice the price is a bit much for the average consumer.
I bought "300" for $22 at Amazon... the HD combo version was $29... That's a better price difference than we see at B&M stores... (anecdotally of course...) The first-gen titles like Blazing Saddles and so forth are coming down to $20 a piece too, which is more in line with what people would pay, but considering the DVD editions are $15 or less, we're seeing yet another cost of entry barrier the studios have _NO_ idea how to fix.... (mostly because they're greedy.)
Anyway... I'll stop rambling now.
