To be honest I'm skeptical of any kind of technology that actually requires a direct neural interface, the ideas that involve this seem to underestimate the sheer amount of trauma involved in neutral surgery and how complicated it is. Not to mention that trusting your average person to take care of themselves on a basic level is "iffy" when you take a look at health concerns and injuries, the everyman with a plug in his head is almost nightmarish, I can just see people poking them, sticking things in them, etc...
Not to mention that there is also the question of affordability, for something like this to become a big deal it needs to be put down into an affordable range, and to be honest I can't see elective neural surgery for the purposes of entertainment ever being something people are going to be able to do as casually as picking up a new X-box or whatever.
Not trying to be a bummer, I've just put a lot of thought into it and run into a lot of back and forth about popular concepts of VR and near future cyberpunk novels and such, and the thing is that while this could conceptually work, the issue isn't the technology itself but the practical concerns surrounding it.
Given my own RL concerns, I've actually considered the pros and cons of having my brain physically examined due to the dent in the top of my head, to see what the damage is, and what might be able to be done. It sounds crazy, but well, let's just say if your where I am now you have thoughts like that. The thing is that simply opening up a head to look at a brain to the extent that would be nessicary would be a big deal, and at the end of the day even if someone DID do it, and could spot a problem, we know so little about the specifics of the brain despite what we've discovered that being able to do anything would be pretty unlikely.... okay consider that, and now imagine someone opening up your skull and then jamming an entertainment or data device in there. 10-15 years? I doubt it. We need a lot more advanced knowledge in the neurosciences, and will probably also require medical automation to the point where surgery becomes easily performed by reliable robots, cutting the cost of training and employing doctors full time, since as I said, nobody that is going to cut into your brain is going to do it on the cheap.
