I think the stories of what happens a few years after the acquisition are much more informative. Given their involvement in the Ruby on Rails community, I'm sure within 3 years we'll see this story show up as a 37signals Exit Interview.
I think Pivotal could be one of those. Him saying "same services" suggests that EMC isn't planning on absorbing the team into something else. It helps that Pivotal is (presumably) very profitable, so there's value to leaving it alone instead of just viewing it as a source of a ton of great devs.
If it's still really Pivotal, and it just happens to be owned by EMC, they might fade much slower than the "everyone leaves within a year and a half" that we've seen so many times.
But thing usually change, quickly, within a year or two.
I'm not arguing against the practice of acquisitions. However, when a HUGE company buys a small team (famous for agile development) I find it hard to believe statements arguing that more resources are going to lead to "increased velocity".
