This could've been answered with a ticket or PM to Alfonso.
Since the weapon balancing put in place, they aren't adding anymore weapons into the shops so as-to keep the values equal to the stats set upon them. (Which were based partially upon price/rarity at the time of the balance)

They could potentially add new weapons, which could be placed in shops.. but I don't see why anyone would be that stupid. The last time new weapons were introduced they were all exceedingly overpowered due to the creators lacking any actual Era experience. This lead to a few bugs and tons of development time (mostly Alfonso) to fix them (mostly RPG).

Plus you guys already complain because stats are too similar or prices aren't correct.
