Since the G70 is currently under non-disclosure agreement (NDA) with Nvidia, motherboard makers declined to provide more details about the product. Nvidia also had no comment on the news as it is its policy not to comment on products not yet released.
The makers did say the G70 may begin volume shipments in the latter half of the third quarter at the earliest and will retail for US$549.
