There's a few things a DSLR will get you that no point and shoot has.

First, big form factor means big sensor which means good shots in low light/fast exposure. Point-and-shooters are a huge handicap at sporting events for this reason.

Secondly, big lenses allow you to get tight depths of field. With p&s cameras, generally everything in frame is in focus. Being able to use focus to pull your subject out and blur the background is hugely valuable.

If you can put a micro four-thirds camera in your pocket you've got some seriously big pockets. But yeah, I hear yah.

I think that movie was called Willow

Let me preface this answer by revealing that I no longer work in the video game industry, as I did not enjoy it enough to stay. A lot of people cut their teeth on writing Windows stuff for fun, maybe working on mods, but a fair amount of developers worked their way up from QA. At least where I worked, it seemed like there were way too many people wanting to get into the video games industry, and once they did get in, they worked their asses off. People would learn to code due to their love of games, not because they liked coding. There seemed to be a lot of very bright high-school guys who, instead of doing the whole computer-science thing at a university, would work QA, and then progress up to be a developer. These people were highly respected because of their commitment.

There was another group of people who formed the more senior developers who got started in academia. People who worked on the engines ususally had PHD's in computer science with an emphasis on graphics. I would think graduate work on game theory or AI would put you in this group.

Being an old-school linux hacker who cut his teeth by contributing to OSS projects, I felt a bit out of place. Most of the guys in the industry don't leave because the idea of working on something other than video games is distasteful. Me, I find lots of engineering problems satisfying.

I used to work for Sony developing PS2 games. The number of people I met that cut their teeth writing code on the linux kit before getting into the business was exactly 0. I might have been the only person I knew who even had a modchipped PS2, everybody else just didn't care since they had the PS2Tool on their desk to do development. Sony is probably discontinuing offering Linux because it didn't spark the development push that they had hoped for. Still, I would think this would limit the number of supercomputer clusters that use PS3's. You'd think the marketing benefits of being a platform in the top 100 supercomputers would be valuable, but perhaps Sony is still willing to work with academic institutions to make this possible still.
