I can't help but think YC would see that, so - unless they expect those companies to be acquired quickly - other than if it is an attempt to corner the incubator market (once they are in every deal, they have all the leverage over both startups and VCs) I fail to understand why they need their batches to be this large. They could have a batch half the size or smaller and pour more gasoline on fewer (better) fires.
A few of the companies seem like ones that could have bootstrapped or funded via kickstarter. They don't strike me as businesses that will make venture capitalists back their money in any considerable way.
All that being said I absolutely love the shift toward hard tech and Africa. But I can't believe there's another 60 to come...
