So with the tenth anniversary coming up (wow, I feel old...), I think that now would be the perfect time for R* to put out a port for the 3DS!
I understand CW didn't sell very well on the DS, but SA could be a different story. If it were a full port, then more people would be likely to buy it. A lot of people love San Andreas and I think it'd work fine on the 3DS! Who else would like to see R* port SA (and maybe even III and VC) to the 3DS?
