There is barely any information on Generation 5 yet.. But going on history,
The original silver and gold(Generation 2) was compatible with Red and Blue(Generation 1) but was incompatible with Ruby and Sapphire(Generation 3) because of the different consoles (Gameboy and Gameboy adv). But Generation 3 was compatible with Generation 4 and they were on different consoles (Gameboy adv and DS). So it could go either way.
But I would guess that Generation 5 is going to be the same as Generation 4 just with more pokemon, Like silver and gold were to Red and Blue, since were not going to see a ds for a few years.
In short: Probably.
