movies companies are dropping UMD from their production line. heres why, with increasingly big memory cards out there, people can easily rip DVD's and compress it onto a sony memory stick to watch on their psp. Plus it just didnt catch on that much and if you want to watch the same movie on your new HD tv,'re going to need to buy a DVD or Bluray version of the movie. So if you're a Spiderman Fan, most likely you have Spiderman 2 on dvd. Then you probably bought the UMD version of it. and when blueray comes out, you will buy a Blueray version of spiderman 2. how many people would want to buy 3 of the same movies out there so they can watch it on different devices.
