I hope this isn't true. For the PSP to be hacked with the same AES keys that were already leaked, they should have learned something. If it's only on dev units and the key for actual production units is different, then Sony has learned. If not, Sony apparently isn't even trying to stop homebrew and hacking anymore. I hope they are smarter than that. If they can't learn to secure their systems, they should bow out of the market humbly, and with what little dignity they have left. A joke is that the n in Sony is actually 2 r's, with one mirroring the other. Sorry.
On the other hand, if this isn't true, and Sony has in fact learned and the PSP Vita hasn't been hacked, then we can at least know they are taking security seriously for once. Until this rumor is confirmed, I'm going to sit back and watch the scene.
