I'm still getting a 3DS, but when I look at what it is that's of interest, it's almost all ports:
-SSF4: Port of the console versions, disappointingly NOT of Arcade Edition.
-Ridge Racer: Not a port, but appears to be another RR rehash re-using the some of the same tracks that RR1+2 PSP, RR6, and RR7 share.
-Samurai Warriors Chronicles: This is a portable version of SW3, albeit with some new features.
-Dead Or Alive Dimensions: Rehash of DOA4 with some extra stuff/old backgrounds and costumes re-added.
-Resident Evil The Mercenaries: Port of the RE5 Mercenaries mode with new characters.
-The other Resident Evil: Look! An ORIGINAL GAME!
-Zelda Oot: Another port.
-BlazBlue Continuum Shift II: Yup, it's a port...and the PSP version looks better!
If the fighting games didn't have online play, I wouldn't even bother with the 3DS at launch.
I"m really really excited to be getting a new handheld system in a few weeks.
Next gen is here!
And by the end of the year the real beast will be unleashed. 
This game looks SO FUN!

I didn't know this version let you control a four-man squad and switch during battle, Warriors-Orochi style. And I see characters from Samurai Warriors 3Z/Xtreme Legends in there. That's pretty cool, however the same week this comes out, Koei is also putting out Dynasty Warriors 7 on consoles, which looks to kick the shit out of all of their other titles.
