I'm assuming I get both bonuses if I use a Studio to flip over another Studio, right?
+1VP seems like a very dangerous ability to put on a non-terminal, even if you don't always control what is your next card, and especially if there's some way for you to get Coppers out of the way. This costs $1 less, gives $1 less, and is not guaranteed +1VP like Monument, but it can be played repeatedly without any help required, so getting multiple +1VP per turn is more feasible. It's why I like Venture more than Adventurer, despite Venture costing only $1 less and picking up 1 less treasure (and forcing the treasure to be played immediately, which can be bad in certain cases).
Also, Studio doesn't do anything for you if you flip over an Action? This is probably intentional, though I think it might make one more reluctant to use Actions with Studio.
Seems that Kelume summed up my concerns very succinctly though.
