I was reading over at DailyTech and Engadget and noticed they both have an article about Sony moving away from the UMD format and going ahead and letting people use their memory sticks to store movies. According to the articles that I read, Sony will start selling memory sticks and a DVD with four movies in a package deal. You will be able to unlock one DVD and transfer it to your memory stick to play on your PSP.
If people can come up with some way to circumvent the “unlocking” process and be able to transfer as many DVDs as they want to any memory stick, then this could be something big.
Yes, I know that there are homebrew applications and hacks out there but this is something that Sony is legitimizing.
