What will be the next new thing for Lego Trains?

Over the years, Lego trains have gone through some drastic changes over the years. The first changes that it went through, was going from 4.5 volt, to 12 volt, then from 12 volt, to 9 volt, and from 9 volt to RC; which is what the Lego trains use today. What is next on Lego’s list? Will the format of current Lego trains set change yet again? With the AC adapter speed regulator, you can play as long as you want with your Lego train, but that only if you have a power outlet near by. With the RC controller, you have limited time to play with your Lego train, but the good thing is that they can be controlled anywhere, and no need to use those electrified 9 volt rails. The 9 volt rails were electrified, so the motor could run on it, without wires attached. the only downside is, you have to have that specific rail to have it run on. The current RC tracks are similar, but is 100% plastic, no metal or anything on it. The only thing is that RC trains can also run on 9 volt rails as well, so it’s backwards compatible. That brings us back here, will Lego drop the whole RC thing, or will they create something new track/controller system in the future? We don’t know, for certain, but we are excited to see what is next for the Lego train series.
