So what should Ancestral Vision really be at?

It was at $25 before the announcement, TCGplayer now has it at $50. Thoughts on what it will settle on? (Also considering if it doesn't get a Eternal Masters reprinting?)
It's ceiling is so high that I can see it staying at $50 but hitting $70+. Even though it has 3 total prints, they were all limited. It's one of those cards that could have a Tarmogoyf or Snappy effect. Every midrange 
deck will want 3-4 copies.

The good thing being that you can't actually Snapcaster Mage Ancestral Vision.

The card isn't actually that good and it isn't highly loved in a variety of formats and/or decks, barring shardless BUG. I see $25 being fair because it's an extremely good card but only in very specific circumstances. I don't expect everyone in the world to be clamouring for one for one to finish decks, only a few people.

The format has changed a lot since this card was legal. Just because it's banned all this time doesn't make it good.
People were excited. Control will see a resurgence. Will this card actually make the cut however? That remains to be seen.
Wizards was smart with this one. Get everybody to brew control. Have everybody realize maybe this card isn't that worth. New decks show up.

Probably experience a similar effect that Bitterblossom and Golgari Grave-Troll had. Spikes hard, then settles down at a decent price after a reprint or it doesn't appear to change the format.
The one card that synergizes really well with it is Goblin Dark-Dwellers. I've been thinking of a Jeskai Control build that plays 2 Desolate Lighthouse and 1+ Goblin Dark-Dwellers with 4 Ancestral Vision.
You get to use your Ancestral Vision twice if it was casted early on, or you just dump it on turn 4 or later via Desolate Lighthouse and untap into Goblin Dark-Dwellers.

Well If it doesn't get reprinted and it is powerful enough to make control top tier,(which I don't think it will because it's too slow) it may become another Tarmogoyf. Otherwise it should level at about 30 or 40.
I'd say just buy them know because we don't know whats gonna happen. At worst you lose like 10 dollars per copy of Ancestral Vision you buy.
