July 18!?  Why.. why that's my birthday!  Yay!!  *feels special*
There are many many possibilities with an SD card.  I think it will mostly have to do with media and not save games.  Like being able to make your own faces for game characters, signs, clothes, umbrellas, whatever in AC e+, or even music.. I think it would be sweet to create a midi file to make songs for the town theme in AC b/c it was pretty crappy using the system they gave you and the notes were limited.  Creatively speaking media would be the reason for that card and I think that is what Nintendo would be aiming at.  Let's just see what happens, kay? 
Your Forum Avatar is too large ... please choose another one.  Thanks. 
Hee hee sorry.  I like the that avatar that says I don't think the rules apply to me.  Good stuff!  Problem solved.  I saw people with much larger avatars than me so I thought it would be cool to use a larger avatar too.  Oh.. geez as for update yeah I meant AC2 not AC e+ which I was careless in reading above posts that its just Animal Forest with E-reader support.  Man I was all excited that AC2 would be coming out on my B-day too.  Oh well lots of stuff during the summer comes out on my B-day but its mostly movies.  I can't ever remember it being a video game despite it being in Japan.
