And not to be overly negative but this announcement would appear to be recognition that HW startups in YC are struggling with a range of issues that required these steps to be taken thus making it even more challenging to assume success in SW will equate to success in HW.
I think you're right. YC was lacking all of the resources that other HW accelerators provide (it's highly specialized). But looks like they now know what HW startups need, so look for YC to be a force in HW.
