1.2 will never have a release bios enabling locks. They say that over several days the use of the beta bioses that enable locks will eventually cause quality control problems.
2.0 - all new shipments to distributers and resellers from asus from today onward will be 2.0 boards. There will be different distributer SKU #'s but same basic model #. The new box has a whitish background instead of green. the new boards will not come with Wi-Fi cards. The same bios will be used for both 1.2 and 2.0, but only 2.0 will see the pcb revision and enable the locks options.
here is the link showing the new sku #'s
it's the one not marked deluxe/Wi-Fi.
Boards should be available Monday. Be very careful as to which version the reseller is still stocking. I'm sure there are still many 1.2's in the reseller channel still, but they are discontinued.
that's about it folks.
