Heya,
Details aren't really available until the shops actually do make an appearance in the next VU. Since we don't quite know what we are getting
But the idea will be that the first batch of shops will be open on an invite basis to key members of retail community, who will provide decent services and products to CND. This is too ensure variety and ensure we have dedicate shop owners who will keep shops stocked.
There is also an idea of having an upgrade process from Market Stall to Shop as a way of upcoming retailers have a way trying out retail in the Resort markets.
The idea is to organise the shops so that they compliment each other and don't conflict too much. At the same time to grow the retail base as and when the population on the resort grows. Finally as Neverdie has mention to keep enough shops in reserve in case real life enterprise wants to test the waters of the virtual universe
