If it's compelling, I'll purchase; I've no allegiances.
Price is a big factor here for me though. I've got a Steam Deck, a PS5 that doesn't get touched, a Series X that rarely gets touched, a Switch that pretty much exists for RingFit Adventure now, and a very capable PC, so I'd need a scenario that makes this device necessary to my current set up at a price point that won't set me back too far, and I kinda have doubts that this will fit into that for me, but I earnestly hope it does.
Xbox desperately needs some kind of win, and the industry desperately needs competition, as innovation is just falling to a stand still lately. Here's hoping they can actually get something, anything right.....but I'm not holding my breath.
