As excited I am for the Switch, getting information like this last minute clearly reeks of poor planning and rushing; with no communication regarding this. Shit like this needs to be planned and ironed out prior to launch. We still don't know about the virtual console shit, if and when Nintendo will address the joy con lag and some others. So yes, if I'm going to to drop a few hundred dollars into a system, I want everything ironed out as much as possible and have every right to feel like this; which isn't an overreaction considering many others feel the same way.
The joycon problem seems to be already fixed according to reports from other users. Anyway we already know that switch is launching (more or less like any other console... Well.. Maybe more) still "work in progress". We'll have to wait until the later months of the year when the "final" online service launches to see what in reality Nintendo is preparing. I suspect we'll have some substancial updates
