The PSP Go must be a sad piece of hardware. In concept, it's revolutionary. It's the first dedicated, all-digital game platform (phones notwithstanding), with full support for the PlayStation Network, several PS3-connectivity features and all the power of the PSP itself.
Unfortunately in practice it's kind of miserable. It costs too much, is saddled with some of the original PSP's flaws (where's my second analog nub?), and digital PSP games aren't cheaper or come out any faster, and in some cases don't come out at all.
Which makes the Dreamy Theater expansion pack to the mega-popular singing virtual idol game Hatsune Miku: Project DIVA all the more of a painful blow, even indirectly. The pack essentially allows Vocaloid fans to play Project DIVA through the PS3 (using a DualShock 3), which in turn upscales and re-renders the graphics to display Miku in high-definition, high-polycount glory. Now you can see Miku prance and sing on the big screen and pretend that she didn't obtain her motion capture data from a 13-year-old.
Worse still, seeing these screenshots of Dreamy Theater just makes me all the more disappointed that there still isn't a full-scale Miku PS3 game. Come on, Crypton Future Media and Sega! DO IT. You'll make bucketloads selling costume and song DLC anyway! Oh, and bring it across the pond, too. Pretty please!
