As mentioned, waiting will not save you anything as far as cost.

However with your V1 serial number, you'll have access to the v2.0 Beta which is fantastic!

Now I'll be corrected if I'm wrong but after you buy V1 you'll still need to upgrade to v2 when it finally drops.

Now if Michael is accepting orders for v2 (at the higher cost) then you'll only pay once but I don't believe he's ready to do that just yet.

The Cost of v2 will be $100US more than the cost of v1.
