It is possible cuz it hinted Sonamy in Sonic X. Really there is no way to know.
I did watch Sonic X, and yea Sonic did say he love her in the Japanese version.. But, Sonic sometimes run away from her and they never ever kiss once in Sonic X or the video games, I'll bet that Sonic just saying that to Amy just to cheer her up...And the main reason why Amy Rose is gaining some much attention because she's based on the mainstream video games. If Sally Acorn was in the video games, she'd might gain some attention then Amy Rose.
As for the Sonic Boom series.. in my view she does look like a total teenager now.. and maybe nearly Sonic's age... I guess we must wait and see until the show starts around fall... And if it does show Sonic love Amy... then the Sonally fans will be done for I guess. 
Btw, if most of you Sonally fans.. if you want to gain her support, then check this out: http://www.sodahead.com/fun/sally-acorn-or-amy-rose/question-1204891/?link=ibaf&q=sally+acorn+or+amy+rose
