Sorry to be the heavy on this one kids, but the answer is a resounding No.
Vegeta spells it out pretty well.
Sylvan library is a decent comparable for proving this cards hopelessness, but you could also look instead to what is currently being played to gain advantage. It's stuff like Dark Confidant, Mystic Remora and Sensei's Top tricks. Skeletal Scrying, which is a fine card and pretty powerful (and only slightly off color) is too slow, situational and risky for the current environment. That card makes Jace look like a three-legged anvil.
Tezzeret, which wins the game, or can get any artifact that costs >5 and put it directly into play, is barely in the current lists as a one-off. Think hard about that for a second. Ok. So, Eastman's right. This will probably fit it into decks making them slightly worse, but still good enough to T8 and have people cook up amazing rationales for how it "won them so many games". It's sure to be a house in other formats, so it won't hurt to grab one or two and be casual-faux-competitive with it. But please don't think this is going to have any effect on real Vintage.

Bumping this thread because the set is released now. I've been playing Jace as a 1-of in my Tezz deck now since the Prerelease. This card is actually pretty nutty. It's not so much that the raw power is overwhelming in any way, but the sheer utility that it provides is amazing. I don't know how many times I've won because I bounced someone's Tinkerbot or Cold-Eyed Selkie and then Brainstormed a couple of times.
He also sets up your Dark Confidants to not kill you if you can't find Top. He hides relevant cards from your hand on the top of your library that you don't want to have Thoughtseized away or puts back that Sphinx so you can cast Tinker.
Just... everything about this card is great.
