There will not be anymore Nintendo Switch announcement from Nintendo until January next year but that does not mean that the people will stop talking about it and that there will not be any more speculations.
The latest rumor suggests that the Nintendo Switch could be coming in with 4GB RAM, that is as much as the 12.9inch Apple iPad Pro is offering right now. While 4GB is double what the Wii U is offering right now, the Playstation 4 and Xbox One is both offering about 8GB RAM right now but it is unfair to compare it that way since the Nintendo Switch was made to be portable as well unlike the Xbox One and Playstation 4.
It will be interesting to see how the 4GB RAM works on the new Nintendo Switch. More details will be announced next year so for now, it is best to take any Nintendo Switch news with a pinch of salt.
