I don't have one but have read all the negativism on other sites. I theorize that Nintendo will only put up with lackluster sales for another year max before pulling the plug ala Virtual Boy. I would only hope they have R&D developing a solid competitor for Xbone and PS4, to be released soon. The risk they take by abandoning Wii U early is angering the loyal Nintendo customers who own one, similar to Sega's tactics with Saturn and Dreamcast. That could be fatal if played wrong. They could always do backwards compatibility between Wii U and its replacement to at least help those to easily migrate to the new system. Only my thoughts, for whatever they might be worth.
I do not own a Wii U either and have no desire to own anymore new consoles at this time.
Are Microsoft and Sony doing great business?
All three look like amazing systems but the last generation still looks strong to me. There are Wii and Xbox 360 games I would like to own. I am sure if I had a Playstation 3, there would be games worth buying still.
