3.15 will offer up at least two new items
for you guys to use on the PlayStation 3. For one, minis are coming to the PS3. Minis are small little games that can be purchased for your PSP and with the next update, you'll be able to play them on your PS3 as well.
The second feature is one that I wish Microsoft would implement. Right now, if you bought another 360 and want to transfer items from the old hard drive to the new one, you have to request for a transfer cable. Update 3.15 for the PlayStation 3 makes it painless and easy as you just connect the two PS3s on the network and use the transfer option. The transfer option is bi-directional and looks pretty simple to use.
