There some psp games i want, but can they be played on the new vita or do i need to get them off the psn store?
I think i can use the usb cable it comes with, like i do with the psp.
Regarding PSP games, anything you own on a UMD will not be playable since the Vita doesnt have a UMD drive. Sony have been looking at some kind of trade in type scheme but at the moment its all speculation. Even if they do do it, it may never get outside of Japan. All PSP games on the store will work however.
You will almost certainly be able to download stuff either on the PS3 store or Media Go on your PC and transfer it that way. A wireless router would be the best option of course since then you can play online.
Playing anything on the 3G version is going to be very very difficult because of latency and ping times. 3G is there for the social features, web browsing, streaming and playing games where it doesn't matter if there is a loss of signal for a few seconds like chess or something like that. Playing Fifa or COD or anything that requires real time actions to be performed just isn't going to work. At all.
Vita needs PS2 games. I hear the PS3 is getting them via the Store, if these can be played on the Vita then that is the best feature ever as far as i'm concerned. Man i hope they do that.
That alone would make me buy one, nevermind anything else.
To be fair, the Vita already has a 26 game launch line up for Japan (likely to be nearer 50 by the time it gets to the west), plus the entire PSP, PS1 and Minis collections that are available on the PSN as well as anything that gets onto the PS Suite which will be a lot of smartphone type games. Adding all PS2 games would be sweet of course but its taken them 5 years to get it on the PS3 with much stronger hardware. Asking for them on the PSV might be being too optimistic.
Some PS2 games have already appeared on the US store and will be on the UK one soon apparently. Initial reviews of the games seem good, they are simply emulated by the PS3 hardware so have the same look as they do if you have the disk in a launch model. There will be a limit to what games will appear as in a few characteristics the PS2 was actually better than the PS3. If any PS2 game used those particular characteristics to the limit then it won't appear on the store to download since the PS3 just isn't powerful enough to emulate it. Those though are likely to be big budget titles that have got or will get a remaster.
I would honestly doubt though that the Vita will get these same releases. It just doesn't have the hardware to emulate a lot of the games. What we have already seen however are some HD remasters being made that will put PS2 games on the PS3 and on the Vita. I expect more titles to start following that as Sony will provide the tolls and it means a bigger target audience.
Already Final Fantasy X, Metal Gear Solid 2 & 3 and Zone of Enders 1 & 2 have been announced for PS3 and PSV.
