Whilst things are a little quiet in the PSP Scene, the PS3 Scene has hotted up a fair bit recently, firstly the release of Freeplays Java Devkit for the PS3 with all the info you need to get you started making Java Homebrew for the PS3.
Also Yesterday Dragula96 released the first 2 Player Pong Game for the PS3 using the Blue Ray Disc Java Runtime (PS3 Java Runtime), now with all the emulators for java that can be found via Google and maybe even more exciting is the recent Java PSP Emulator being written at this time, now it doesnt support games etc at this moment but in future it should do but imagine the same emulator being ported to PS3 Java, a PSP Emulator on PS3 would be pretty awesome.
