A new version of Sony's PlayStation Portable games console is expected to be launched at the E3 video games show.
Video and photos of the PSP Go have been leaked online, revealing a smaller, more lightweight console that has dropped the failed UMD disk format.
There have also been reports that Sony will announce a re-designed, slimmer PlayStation 3 but BBC News understands this will not be launched at E3.
The new PS3 model will be out later this year, BBC News understands.
Sony is expected to unveil the PSP Go on Tuesday, following a number of high-profile leaks of announcements to come out of the firm in the last few weeks.
The most recent, about the PSP Go, came after an official video showcasing the new device was mistakenly posted to a Sony website before being hurriedly pulled.
In the video, Sony's John Koller said: "It's a 3.8-inch screen, it's 43% lighter than the PSP-3000, 16 gigs flash memory, Bluetooth support and all digital content so the UMD drive goes away.
"So it's going to be something a lot of consumers like - download straight to a hard drive."
A spokesman for Sony would not confirm the launch of the PSP Go but said any announcements would be given on Tuesday.
