Congratulations on your new son, and I hope your wife has a speedy recovery from her surgery!
On topic, as someone who is just entering the "maybe it's time for kids" stage, I've given a lot of thought as to how I would handle it if my kids became avid gamers like my husband and I, and the conclusion I have drawn is that I'm going to have to trust my instincts and do my research. Unlike my parents (who have no interest in games), I look forward to gaming with my kids, so I plan on using the tools on hand (like the internet and ESRB ratings) to determine whether or not a game is appropriate and playing the games myself to make sure. If I find it inappropriate, I won't let them have it. Simple as that. Lucky thing for my future spawn that I have a low bar for appropriateness - by 8 or 9 I think the only thing I would restrict would be games with gratuitous sex, as I myself was playing pretty violent stuff at that age and I turned out ok. As for consoles, I think that I wouldn't restrict any if we could afford it, and some would be extremely handy for keeping them quiet on long car rides.
The bottom line is, video games aren't going to hurt anyone's precious snowflake, and neither is the lack of them. It's up to parents to decide what is appropriate for their children, and what they can afford, on an individual basis. Besides, you may have bigger problems to worry about in 16 or 17 years.
