woah that looked pretty awesome already! damn I'm happy sony went with a system with the ease of porting. 

Very promising. It seems like the PSV is the sysem of choice for fighting on the go. I'll definitely pick this one up. :)

Now if that Tekken rumor becomes true....the ultimate fighting portable system evah

It just needs a new Bloody Roar game

Duuuuuuuude! Bloody Roar was awesome! (Well up to BR: Prime on the Gamecube). The second and third installments were my favorites, and I think 2 on the PS1 was the pinnacle of the series. If they made a proper Bloody Roar for the Vita that would definitely be a day one purchase for me.

Does All-Stars have cross-save ability?

yes it does. Its sort of strange though.

You have to be connectet to the psn in the game for the saves to sync, basicly you need to play an online game.
All there really is to save though are the caracter levels and the unlockables that go with it and if you gain 20 levels on ps3 and then 20 on the vita without syncing and then sync them they seem to accumulate and you have 40 so i you don't really have to sync right away.

Also the trophys don't sync you have to earn them on each system seperately.

Yeah the ones on ps1 where the best. So much cool characters, insane beast mode finishers, amazing arcade sounds and of course the mini beast mode was hilarious XD. I think 2 or 3 where my fav and I was so disappointed with 4 on the ps2. Odd though I dont remember the story at all.

The company who made them are now owned by Konami and to my knowledge I dont think they made any other fighting games. And Japanese companies love fighting games :P. I'd kill for a new Bloody Roar game on the vita.

So I need to play an online game for my saves to sync?

yes. or that's how i do it.

That's the only way it works for me.
