(SR4) Price range of the new A77/NEX-7 and NEX lenses

One of my good sources sent me the price range in USD dollar of the upcoming new A77 and NEX-7 (+ NEX lenses)

Sony A77
Body only will be priced at $1000
Body + 16-50mm f/2.8 SSM Kit will be priced between $1600 and $1800.

NEX-7
Body only will be priced between $1000 and $1100.

NEX lenses
Zeiss 24mm f/1.8 will be priced between $900 and $1000.
Sony 50mm f/1.8 OSS Zeiss 24mm f/1.8 will be priced between $300 and $350.
Sony 55-210mm OSS Zeiss 24mm f/1.8 will be priced between $250 and $300.

I asked the source why there is a such huge price range for the A77+kit lens but I still didn’t get an answer yet.
