Thanks to reader Ben Torode, we've got a proper translation of this http://www.watch.impress.co.jp/game/docs/20080701/ps3up.htm article, detailing a number of new features coming to 2.40 not yet mentioned by SCEA, as far as we know:
1. The way to quit games has also been modified in line with these changes, and a game can be exited by pressing the PS button during a game and selecting "Game" then "Quit Game" from the XMB.
2. On the XMB in general, added functions include a clock displayed on the XMB, a function to delete all entered text in the entry field when using text entry with a keyboard, and a function which displays an icon to indicate when operation of the PS button is disabled.
3. In "Users" under the XMB, an item has been added to power off the PS3 console. Under "Settings", options have been added to automatically power off after a system software update, and "assign controller", "controller vibration function" settings have been added under "accessory settings".
4. Under "Photos", as well as photos within a playlist becoming printable, when photos are sorted by month or year taken, an ascending and descending order option has been added.
5. Under "Music", a mini control panel can now be displayed while playing music, as well as "MP3 Surround" being added as a playable file type.
6. Under "Video", "Frame Noise Reduction" and "Block Noise Reduction" can now be configured for vidoes stored on the HDD or storage media, and upconverting output is also supported. Additionally, Blu-ray Disc upconverting, DVD Video DTS-ES and DTS 96/24 and Blu-ray Disc DTS-ES Matrix playback is supported.
7. Under "Internet Browser", "Search" has been added to the menu. Under the friends list, the number of friends that can be registered has been increased from 50 to 100, and the information screens of friends redesigned.
Yeah, Luckily alot of this is useful. If I can just get my hands on a game that has trophy support I will have it made ... Wonder if they will change the update number when they fix the issues or keep it at 2.4?
I would assume that they would need to put a higher number than 2.40 for those people who have their ps3's bricked. They would add more things in the next update than just what has already been put. Perhaps it checks if you have 2.40 already that you dont need to redownload the content that has been released.
I've been encountering some freezing issues since I upgraded to 2.40, mainly when I try to start MGO (though MGS4 hasn't froze yet) and it happened to me with MK2 as well. Not fun, I scarcely had any freezing issues in the 9 months prior since I've had my PS3.
