She also tweeted about the Switch's reveal back in October, and about the launch of Super Mario Run. How many Monolith Soft announcements in those 2 events? I didn't bother to look further, but she tweets quite a bit so I'm pretty sure she didn't talk about Nintendo the 2 times when her husband made announcements only.
I'm not saying there will be nothing at the Switch event from Monolith Soft (it seems logical to think that there will be something from them), but the "argument" here reach an all-time low.
Oh, she tweeted about the October reveal? I wasn't aware of that. After all the recent rumors I do think XCX is going to be at the upcoming event.
