Do you think NX will be a success?

No.
Nintendo have burned everyone at this point, including their loyal core fanbase.
No matter how good NX is, consumers will be wary of buying into it for fear that they'll once again have to put up with constant game droughts, delays, and not getting the games they want.
It's late 90s Sega all over again; Wii U was the Saturn and NX will be the Dreamcast.
