if/once nintendo starts locking services behind its networks and tons of upcoming updates it gonna make the switch unplayable for me. ps3 did the same thing with netflix/youtube by requiring a log in and it really made access to a simple video service that much harder, then they kept adding that huge firmware update every month with all the hackers shutting down psn and locking everyone out of those services. The same thing happened to the VITA, moving files to and fro required internet connection alongside an update every other day.
the biggest problem for the wiiU was locking the wii into a whole different section, making something that shoulda have been simple into a 3min process, the wii had a huge install base with the elderly and im sure it made it much difficult for them to play simple wii games as it made it incredibly tedious for me. The switch solved this problem by making their interface simple much like the wii did by just having a picture to point and click
now when it comes to Nintendo's new service they will roll out in fall '17, I forgot to put a mention to the virtual console stuff, im not talking the neo geo stuff im talking the future gamecube and wii stuff, it would be horrible if they locked it behind an internet check or update.
I want to write a lot more but Im thinking about when i take my switch as a portable and how all of this stuff can be a disaster, if your sitting at public wifi place and then you log into its garbage wifi and the auto update doesnt fully download, or your leave said place and it just messes everything up. splatoon is definitey not a game you can take on the go unless you own a very expensive phone hotspot plan.
I guess all im really saying is locking services behinds its own service would be a bad thing to do especially because its a portable system and ive already experienced the psvita
