Put Team Fortress 2 on the PSN store including all the updates and ALL the trophies.

Basically a program that is accessible from the XMB in the Network section that is specially made for the PS3, versus using the internet browser for Wikipedia. It would have an offline mode too.

Lithium batteries similar to that used on the dualshock3, but for the PS3 blu-ray remote.
This idea may also extend for other wireless controller types, such as the Guitar Hero wireless guitar.

A playstation 3 controller that has a push to talk button for your wired/less headset, to prevent having to mute and unmute yourself, or un needed noise communication

You can buy them on the US psn, I would love to be able to purchase them here in the uk.

Moreover, why not have the psn just offer ALL of the themes and dynamic themes worldwide?

Add trophies and port classics like Abuse, Bioforge, Crusader series, Cybermage, System Shock, Ultima series and the Wing Commander series to PS3. Either on PSN or even a BD with all titles.

I find it quite silly that it isn’t possible to sort the titles on as memory stick, when using the PSP. Could we change that? A-Z, Z-A, Most played, lest played, & or one, someone else can think of.

exclusively on ps3

A usb memstick that works like the memory cards of the ps1&2. Copies copyprotected files and downloaded games for play on other ps3′s, but only saves to the harddrive of the ps3 the files came from.

Where’s my controller? How about a way to rumble the controller when you misplace it by holding the eject button or turning on system. The rumble can help locate ur Dual Shock when u cant find it.
