If we DO see the other Mane 6 members become Alicorns, it should only be in a.) a fantasy or "what if" episode (like Power Ponies) or b.) the last episode.

And remember, the alicorns are also princesses. I could see Princess Rarity (though I think she'd hate it if she couldn't continue in fashion), but I doubt the other four could do it. Princess Pinkie Pie would constantly prank her subjects and pass joke laws. Princess Fluttershy would have a hard time facing the public (an important responsibility for a leader). Princess Rainbow Dash would be too caught up in how cool she is to be an effective leader. Princess Applejack might be up to it, but she'd miss Sweet Apple Acres and her kin in a heartbeat.

And, judging by how the Season Four finale ended, I think we can say they're now Twlilight's co-princesses anyway.
