The armour prices were rasied just to give the player something to aim for(so not likely to be affordable as soon as possible) and to make the prices wider between the lowest armour and the highest. So that if you are able to buy the best weapons you will probably be able to buy the best armour, low armour fits more with low weapons etc. All the 'top tier'(Best) items are in general more expensive than they were, but that is more in relation to ship prices than it used to be.
And as making lots of money isn't really an issue in this game, you'll be able to afford the best stuff, just not(probably) in the first 10 char levels of the game. So yeah most of that kind of cost rebalancing is just to give the player stuff to aim for over the longer term(so they have new stuff to look forward to from level 10 and over). It would be nice to have more stuff maybe(say more armours etc) but that takes work and creating items etc, rebalancing the costs to spread things out a bit more is the easier option currently. Also keep in mind you can play this game to around level 30-40(Hylie has anyway!), you don't want all the stuff as soon as possible and then nothing new for the next possible 2/3rds of the game!
