I have done some calculations out of interest. Please correct me if I made a mistake somewhere in my reasoning:

@ 2min per block

Phase      Blocks   Reward                  Coins     Minutes     Hours     Days  
1             1,000            1                  1,000              0            0          0 (negligible as completed in first few minutes)
2             9,000        500           4,500,000     18,000        300   12,50
3           10,000        250           2,500,000     20,000        333   13,38
4           20,000        100           2,000,000     20,000        667   27,78
5           20,000          50           1,000,000     40,000        667   27,78
6           40,000          10              400,000     80,000     1,333   55,56

               Total POW                 10,401,000   198,000     3,300 137,50   = 4,58 months (pretty long time to have ASICs off BTC if it will really take this long)

From 10,401,000 to 50,000,000 are POS coins.

POW will therefore take 4.58 months since POS and POW are not simultaneous POS will start in 4.58 months, or at which point does POS start?
