With luck, it's just some of the more extreme glitches utilizing the out of bounds hacks that will be affected and not the relatively simple floating tricks we use. But I won't be surprised to find items we had floating away from walls and floors snapping back to them because the game decided they were close enough.
I missed that line, it was getting early by that point. It sounds like Yoshi isn't sure what, if any, impact it would have on housing but acknowledged there could be an impact.
Last time they made a change to housing glitches it was the ability to put things in the void. At the time, anything that was currently placed in a void would stay there but you couldn't do any new placements. Most likely this will be similar, anything already in place will be unaffected but anything new may be more difficult to do. Because he's talking about collision the changes are probably in the bounding box and how many interaction points it has for detection. I don't think they'd change the size of the bounding box for every item in the game; that would be a nightmarish amount of work. If its just detecting the bounding box then it will mean you can't float things as far into the walls or ceiling as before and some objects like the display cases may not overlap as much.
