Is it just me or are there going to be WAAAAAAAAAY less coins than stated in the OP?
From the block reward source that ocminer posted this is the total (there may be more but the source posted only goes to block 8640)
Blocks Reward Coins0 - 119 0 0
120 - 719 1000 600,000
720 - 1439 500 360,000
1440 - 2159 1500 1,080,000
2160 - 2879 500 360,000
2880 - 3599 10000 7,200,000
3600 - 4319 500 360,000
4320 - 5039 2000 1,440,000
5040 - 5759 500 360,000
5760 - 6479 2500 1,800,000
6480 - 7199 500 360,000
7200 - 7919 3000 2,160,000
7920 - 8639 500 360,000
So the total coins up to block 8639 is 16,440,000
Assuming that I have worked that out correctly!

I have just gone through all the 10,000 reward blocks (actually was 2881 - 3600, not as above) and counted the number of POS blocks during that period. The number was 250 POS blocks which equates to the total amount of coins being reduced by 2,500,000 for that period. There were 470 POW blocks of 10,000 totalling 4,700,000 RVC.
After block 3600 the total coin supply was currently sitting at 9,255,570 (according to C-CEX) but this includes the premine of 2,500,000 for the IPO, so the total number of POW coins was 6,755,570 after block 3600. This is 2,844,430 short of the amount that it should have been at if POS had not started until after POW.
If we take 250 POS blocks as the average per 720 blocks then the new table would look like this:
Blocks Reward Coins0 - 3600 6,755,570
3601 - 4320 500 235,000
4321 - 5040 2000 940,000
5041 - 5760 500 235,000
5761 - 6480 2500 1,175,000
6481 - 7200 500 235,000
7201 - 7920 3000 1,410,000
7921 - 8640 500 235,000
So now the
estimated total coins is 11,220,570 + the 2,500,000 IPO.
