What is Geohot's motive? He strings everyone along after he initially found the exploit without sharing any information. He decides to leave the scene because he was tired of the negative attitude. And after fail0verfl0w comes out with their finding, he suddenly reappears to share. For someone who was tired of the scene, he sure does love to stick his head back in as to say "hey guys, look at me!"
I congratulate everyone in this awesome day of Sony fail! It's so awesome, so I can't even describe in words!
I really hope, that now somehow implementing MKV fomat will be possible on PS3 via players or natively. My fiancee's dad is going to buy el cheapo Samsung LCD and it does have MKV native support indeed, it's a SHAME PS3 don't support it.
Also, implementing some file format as ext3 / NTFS for extarnal storage is going to be awesome. I don't think it's miles away, because Wii didn't have USB 2.0 compatibility, and now because of the homebrew it even has NTFS support!
