i don't really see the point of an exploit that won't allow backup managers.. meh whatever..
It depends on what you use your PS3 for. If you just want homebrew, then it's a good step forward. For example, Showtime should be possible. I know the lack of NTFS and MKV support is a sore point for a lot of users.
Yeah I'm not overly concerned with Peek and Poke not incorporated yet as most CFW start like that then someone else adds the support later.
Good to hear that Sony didn't get round to patching the exploit in the Major update though
And I believe that MKV support was added into showtime and NTFS support is available using Deank's MM - correct me if I'm wrong though as I don't use either feature.
