First the update:
Well, I was reading on the Blu Ray site and although Warner will be releasing all the Harry Potter movies on both formats, they've actually decided to go strictly Blu Ray probably next year, since sales of 300 in Blu were extremely impressive (it was the first Blu Ray I bought too^^) Sooo for those thinking of HD the ONLY studio selection you'll be able to buy from, are Paramount/Dreamworks and Universal. That's about it. Even then, I think Universal has given in to Blu Ray a bit, since apparently DVDs marked as 'Alliance Ent' say Universal on it at my work and I've seen them as Blu Ray, but I'm not too sure if they really are from Universal (all I can find is New Line Cinema), or if they usually get returned WITH Universal DVDs. But yeah, that's where it's at. Oh, and don't forget that since HD isn't too global, that anime will probably be strictly Blu Ray too.
Ok, onto part 2...
What I think is personally the best part of hi def? The disk cases! The enormous space and hi quality is awsome, but personally I LOVE the cases! Honestly, I've NEVER understood why DVD cases have to be tall, it's REALLY unnecessary AND you have no idea how many loose disks I've come across at work :/ Trust me, it's not fun buying a brand new DVD and finding out it was loose, shaking around the case and scratched up :/ So the shortness seems to solve it. Also, the skinny factor! It allows the shortage of maybe 1 disk in a boxset, but can still be real skinny, like my Planet Earth box set. Skinniness saves on space too, and really, that extra wide space isn't even necessary unless it comes with a huge booklet, and once again susceptible to becoming loose :/ With game cases, Game Cube and PS2 actually NEED to be tall for the memory card slot, but I still have no explanation why DVD cases are so tall (anyone even know?) PS3 cases are nice too, short but still a little thick for the booklets to go with it.
So yeah, that's my info/thoughts for the day. Comments?
