Not seen anything involving this on the forum, soooo....

For those lazy to read the link, essentially, Sony & Panasonic tag-teamed and came up with a new evaluation method for reading data off of a BluRay using existing hardware.
What does it mean for us the consumers? Well, if your hardware supports it (all PS3s will have it via a firmware update eventually), Blu-Rays will have the potential to sport an extra 8.4gb per layer, which means disc sizes of 33.4gb SL, and 66.8gb DL rather than 25gb & 50gb respectively. Sexy is all I can say given this works on existing hardware with an update.
It won't mean much in the gaming world for quite some time given MGS4 is still the only game to get close to the 50gb barrier (31gb of fully compressed data, hence all the installs required), and probably would have been the only game out currently to benefit from this new tech. Only other game that high off the top of my head is FFXIII with 37.6gb space used, but more than half of that is just 1080p FMV video apparently?
(would explain how they were able to get it to fit onto 3 DVD-9s for 360, just rape the quality of the FMVs and you're good to go)
What I'm personally interested in though, is whether or not the new reading method they'll be implementing will be faster or slower than the existing method. I'm assuming slower because I'm cynical, but if I'm wrong on that, this'll be a nice treat given it may help alleviate the fact BluRay players have shit seek times, and may result in faster load times on future games, and those damned fancy-smancy BluRay film menus that half my movies like to spend 15-25 seconds loading.
It may be great for movies (LOTR: Extended in 1080p 1 disc per film in the trilogy plz), particularly if '3-D' versions require the extra space, but for games? With most features being multi-platform these days, they're hardly taking up even half of a single normal bluray disc thanks to the 360.
(am I the only one who's bothered by compressed videos on a PS3 port of a 360 game?)
On the same subject, Blu-Ray 3-D specifications were finalized mid-December, so from the sound of things 2010 will really be the year this 'fad' as many like to call it will be hitting the mainstream hard, more-so with publishers jumping on board for it (Disney and Dreamworks are already confirmed to be working on 3-D editions of their upcoming releases), so it'll be here to stay whether you like it or not.
Incase anyone asks, why do I use the dash in 3-D? Because it's the simplest way I can think of easily differentiating 3d as in cgi graphics, and '3-D' as in visual depth perception. Also, tried my best to keep this the least wall-of-texty as possible.
