It's pretty much guaranteed, seeing the success of both the Gen 3 remakes of Red/Blue and Gen 4 remakes of Gold and Silver.
Personally I won't mind them, as I didn't get to play neither Ruby nor Saphire, instead went to the daddy of the two, Emerald 
Edit - My last phrase sounds all weird for some reason. I wanted to say that I didn't mind the remakes, and I will still buy them. My crappy english does this sometimes, I guess.
