They could ported to console, but it clearly not something outside Nintendo's consoles. Its impossible for them to let go one of their flagship series while they're not experiencing financial trouble or some sort.
If you mean by the
Main Game ported to console, yes, its better to stay in handheld.
But if we take to wider horizon, it could work really.
The game itself must be the more complex version than those in handhelds. That is a must since console hold more power than a handhelds.
The game could be total spin-offs or still related to the main game.
I'd love to see some (truly) new life breathed into Pokemon. The DS line it's on is nice and all - it's definitely pleased the dedicated fans and brought some new ones in - but it's been moving at a terribly lazy pace over the years. I think I've mentioned on another thread, Pokemon hasn't grown with me. Black and White were mostly nostalgia with pretty ribbons on it.
I have zero reservations about everything from a complete rework of the battle system to trying genres Pokemon has yet to branch out into, let alone a jump to new consoles. I don't think it would be a good idea to abandon the traditional games altogether, though. That's what's been bringing home the bacon.

Pokemon doesn't make any groundbreaking change since generation III(by changing the whole IV and EV system).
It just keep stalling these following years. Hoping for battle system to change or at least to be improved is just like wishing for hell to freeze.
Although, by making a port console it doesn't mean it have to abandon the portable version all over.
In my mind, I know that the main Pokemon games are probably always going to be on handheld Nintendo consoles; in my heart, on the other hand, (and I can't believe I said the phrase 'in my heart'!) I really would like to see the same Pokemon gameplay up on a television screen or hologram-3D-mind-meld-thing or whatever the future of console video gaming is. I've said on numerous occasions that the basic structure of the Pokemon narrative needs to evolve if it doesn't want to hemorrhage fans, and while I don't think the same will happen if it stays on portable devices, I do think that it would be of great benefit in the long term if the idea was floated around. But, that's just me... I imagine I'll be in the minority on this one.
IMO, Pokemon narratives are among the worst from the biggies franchises.
It is not because the limitation that make Pokemon narration that bad.
It just Game Freak doesn't really put much effort developing the narratives.
