Yes, there is an IR Pointer in the Joycons
No, there is not. It does, however, have an IR camera and I think it's only Labo that uses it (and damn well, also). Yes, I know that there is a cursor there but that is controlled by the joy-con's gyro since the joy-cons do not have IR pointers.. A lot like everything in Zelda SS was controlled by gyro (that game did not make use of the IR pointer at all). And the problem with gyro vs IR pointer is that gyro has to be calibrated at times (as in Zelda SS, or even World of Goo.) I have WoG on Switch and Wii BTW, and notice the difference.
Your GameExplain link even said so! Your very own link!
I think we are misunderstanding each other here. Hope so at least.
And it's not about me thinking I am always right. Everyone can be wrong, but in this case you are (or we misunderstand each other, as said, somewhere)
Cheers! Going back to Ultimate =)
