Well..... I got an X-T5 after seeing the X-T50 lol.
I managed to get it last night on sale from £1700 to £1450, I'm going to sell off my X-T30 and a lens which will make the X-T5 cost only £700 afterwards - which is quite a nice upgrade. Already finding IBIS amazing for macro work. I think the only other reason I wanted it was for weather sealing when travelling and the 40MP is great for landscape / Wide angle work and maybe some film scanning in the future. Also going to use it as a webcam. Hopefully this camera lasts me 5 years as well.
I was going to get the X-T50 but the price is not justified for the features it offers, plus the rumours on that camera make me feel that this isn't the camera for me anymore. I do notice the weight difference between them though, especially with a grip so might have to consider not using the rope strap as it does hurt the neck if you're using it for the whole day.
