It is very feasible 3DS will see a GTA. I can see good cause as to why they should do one. But I wouldn't nessacarily say it's 100% certain. The only thing in life that is 100% certain is that one day it will end in death. Morbid but true people.
On a personal note I just hope that if it does happen it's a proper GTA (like 3, VC, SA, Stories) and not the travesty of a GTA that IV and Episodes were.
