It can fall all the way, as far as I'm concerned.
Historically, Sony products were high price, high quality, but somewhat lacking in leading edge features.
Now Sony has downgraded it's quality control, products are still lacking in leading edge features, Sony is in the process of downgrading already sold products effectively peeving off what little loyal customer base they have established, and the price is still significantly higher than competitors products.
Good luck with fading in obscurity, Sony!
Although, I'm sure Sony won't need my best wishes, as they're doing a great job already.
