I'm not "promising" anything. Most of my posts start with, "...if the SCD patent is true" or stating that if it comes to fruition. All I'm saying is that people in here are jumping to conclusions before knowing the full story. I can almost guarantee we don't know everything about this system from that leak. Look at the reports--nobody is even sure what the TV connection/dock is. I'm not saying it's used to boost power to the system, I'm just pointing out that people don't even know what it does yet. Nobody knows the finer details yet and probably won't until the official reveal. If they announce at the reveal that this thing is never going to be able to be upgraded, by all means--complain away.
As for the future, I just think it makes sense to utilize that system of upgrades. It also helps Nintendo when it comes to R&D costs--by sticking with the same console and just upgrading power, more resources can be used for game development, etc. It makes sense for Nintendo to go this route. Is it guaranteed? No. I never said it was. But it seems like the way for them to go.
