No, they should never have removed the Gamepad nor should they.
They should have revised it though, make it cheaper by the way and get some decent marketing. Especially the EU marketing was, well, plain shit, sorry to say that.

I find the gamepad to be a novelty for basically 95% of Wii U games. Most use it as a 'map' or it replicates what is shown on the TV anyway. It is just an un-needed expense unlike the Wii motion controls which were integral to most of the defining games on the Wii. The majority of people just don't see it as justified much like the Kinect. Just my opinion.

I agree, people don't always care about logic, but let's use some logic and try to find a source that proves that Gamecube made a profit. Or that WiiU has made a profit so far (not right now, but overall). While we're at it, can you tell me how exactly you know that Ninty did not consider Gamecube a failure? A failure does not mean sell x number of units, make $5, etc. It means the company has certain expectations and the product fails to meet them, even massively. 

If you don't wanna address all the points, please at least provide that source that I've yet to see ever posted. I, like you, like logic too. 

This means nothing. Its well known that Nintendo start working on their next console not to long after releasing their current one.

Nintendo talked openly about a succesor to the wii in the summer of 2010 and the wii U was released in late 2012. Nintendo has already started openly talking about a succesor to the Wii U this summer. Therefore following history a succesor to the wii U should be released by late 2016. 

Of coarse this is speculation.

What games are you playing because most of the games I have played uses the pad is used well. Having your menus at a glance rather than having to pause is a plus and worth it. I wish I had the pad for Zelda orcarina of time. Constantly having to pause to changing boots in the water temple became a pain.

I agree that it is quite concerning to see Nintendo talking about physical details of their next console so soon. Sure Sony/Microsoft are probably working on the PS4/Xbox2 right now but I certainly do not see them taking the focus off their current consoles by revealing details publicly a mere 2 years after their current consoles were released. Nintendo have always been quick to jump ship when their current console doesn't sell well. They announced the Gamecube in August of 2000 just under 4 years after the US release of the N64. Naturally the software efforts from Nintendo and their first/second party developers diminished greatly after this. The GCN was released in 2001, a mere 5 years after the N64... The Wii was released in 2006, also a mere 5 years after the commercial disappointment ofthe GCN..

Come on man... Having the screen used as a menu is not a pivotal reason for the gamepad. Games like NintendoLand use the gamepad much much better. Games like that actually showcase how the screen can be used in an innovative and functional way, not simply for displaying a map/menu/health vitals.

But if every game tries to pack every possible uses then people will complain it is forced like the waggling complaint of the wii mote. Just use it as needed. Some games need it more. Some less. Like I said, most game use it well for what ever game it is. No a menu is not needed but is sure is better to have than not. I find that some games a map is good like low pace games. Where as fast pace games is better on screen. Its a learning curve. But is being done pretty well all around.
