What should happen in the Season 4 Finale? arco iris Power o Mane Six Alicorns?

I think i'd be fine with arco iris power as long as the episode was executed decently (also...if there are so many arco iris stuff that has to do with the mane 6,why didnt they just made RD some kind of chosen one? -_-) besides there are enough alicorns for me...

arco iris Power. I have seen enough alicorns. It would drive me crazy seeing five more!

ALICORNS FOREVER

arco iris power

Nether :P

arco iris Power. The mane six alicorns is never going to happen! But I am still counting on there being an Alicorn Fluttershy!:)

Definitely arco iris Power.

SPOILERS: It's already settled. Rainbowfied Mane 5 and Twi will get to rule the newly discovered arco iris Kingdom.

I think I'd like them all to become alicorns and for them to later on discover a new kingdom and rule it together so that there aren't too many alicorns in Equestria. My reasoning is that if they are ever attacked when they are alone, they should be able to defend themselves.
