Nyko has announced a new line of gaming products at this years Consumer Entertainment Show (CES).
The PSP specific items that are currently on the show floor are:
PSP on TV Converter
Charger Grips for PSP
Theater Experience PSP
Power Tuner for PSP
There are also a few XBox 360 products available as well. No pictures or additional information is available at this time but I am sure we will see them soon as CES is a major high profile show.
