I'm pretty sure it's a "when", not "if".
Also, the Neo is just cheap enough that it's a product I'd consider buying that I don't need. I'm not in the market for a new laptop and certainly not an Air. So I'm a demographic considering this product that is not going to cannibalize their existing sales. There's gotta be at least a dozen people like me!
And just give even a metal plate on top of Neo SoC would have increased its thermal capacity.
