As mentioned in an ESRB Watch last week, it looks like Sony is wasting no time in getting these released.
I see an unannounced WipEout table in that video
Jason Coker a Producer at SCEA had this to say on the PSBlog:
For me, the coolest thing about Pinball Heroes is that if you dig pinball, you’ll really like any of the tables because of the diverse set of challenges that each one features, including an in-game trophy shelf, in-game trophies, online leaderboards, and an assortment of modes that keep the game exciting and fun. On top of that, if you’re a fan of the titles that we represent on each table, you’ll really enjoy the way we’ve incorporated the flavor of each game into Pinball Heroes.
Each table will cost you $3.99 and we will have reviews for all 4 tables up this weekend.
