yes there is PJ5 and more models. Im setting my eyes on PJ260E. But looking for some guys who would have opinion on it. That will help before buying. Personally im too impressed with this feature, i share tips on share trading etc will help in shooting & showing market videos right away. I saw sony's talking a lot about it on their website etc. i have asked them on their user forum at *www.facebook.com/SonyIndia/app_104098299713273
