I want to see all that Wii had and good number of GC, Wii and Wii U games. Also I dont want to wait again for VC titles that are already on VC Wii U.

cheaper prics and the ability to transfer your purchased vc games you bought on your wii wii u and 3ds to the nx vc

If Nintendo goes x86 or ARM cpu, both have emulators that can play nes/snes/gc/wii games.

Nintendo just needs to talk to those people and get some of that code, and integrate it into their system.
All nintendo titles up to the Wii playable on the NX.

then they need to cut all those games prices to reasonable rates (2-4$).

I don't want it to end the way the Wii VC ended, I think it should be some kind of service, that is on both platforms and will carry on to the ones after the NX
I think they should bring it to mobile and PC too.
A pclient like Steam, but only with retro gaming, of course it should be an emulator and depending of the platform you could emulate different platforms. It should cover all the consoles Nintendo made before the Wii. Problem with the Wii is that controller...

They should create a team dedicated only to porting games to the service and taking care of it.

As for the prices HylianYoshi is spot on 

NES/Master System/Game Boy/GBC - $2.99

SNES/Genesis/GBA - $4.99

N64/Saturn - $6.99

GCN/Dreamcast/DS - $9.99

Wii - $14.99

That's a great point. I have found that even now most of my VC gaming has been on the Wii. The Virtual console on Wii not only has more games, but a significantly larger number of RPGs, and games that appeal to RPG fans.
