I could see the Neo replacing the Go. However, what makes me hesitant is the (likely) high price of the Neo. Assuming there are multiple hardware tiers, the lowest I'll go is around $749. And that's just a guess because we still know very little about what will be inside. I think a lot will depend on where Microsoft wants to shuffle it's current userbase. Microsoft could attempt to further diversify their ARM offerings next year with a Pro X 2 and an ARM powered Go 2, which would probably use one of the 7c processors Qualcomm recently announced. *fingers crossed* And maybe 64-bit emulation will be ready by then. Thus making the low end Surface Pro the spiritual successor to the Go. That would shift Go users, or even those looking to buy a Go, to a higher tier device if they need to stick with Intel. Or maybe Microsoft introduces a Go ARM and Go Intel. There are just so many ways for this to go. Either way, I do think there will be a reckoning and certain product lines will get the boot. (I'm looking at you, Surface Book)
