I do agree with you as its basic electronics economy, two years ago a surface pro 4 was a £1000 item but nows its cheaper to make and their are deals to be had, this has resulted in the pro 2017 so MS can keep a premium product and add the changes they couldn’t for technological or economical before.
I’m eager for my V and it shall still be cutting edge not to mention unique in the electronics space, but it will have competition not far behind unlike it would have done for longer, resulting in a certain amount of shine being removed.
For instance would the world have been so amazed with an iPhone, if another company had a similar device out just after, I don’t think they would have but it took most of the mobile space just under a year to react and poorly.
Or 10 years ago my external hard drives were £70 for 12GB! Now 10GB is £7 in a USB stick format.
