I think the point that OP is making is that price-wise, WP does not compete very well. People say that its not fair to compare the 635 to the Moto G for example. Some on this forum have said it should be compared to the Moto E. Specs-wise I'd agree, but price-wise, no way. Here in the UK the 635 and the 4G Moto G are very close on pricing (in some stores less than ?10 between them). Using that as a gauge, the 730 is likely to be quite a lot more expensive than the Moto G which will be the phone it competes with on specs. I'd probably say it'll be ?199.99 here in the UK.
Similarly with the 930. It's price at the moment is extortionate! Considering the age of the processor inside the phone it should not be retailing for over ?100 more than something like the Xperia Z2.
When your average consumer is inside a phone store and looking at a phone, they will use the price as a benchmark, not specs. They won't care that Nokia want the 630 to compete with the Moto E, the price tells them that its competing with the Moto G. This needs to change.
Having said all this, I enjoy my 635. Love the green colour!
