Also the growth will probably be less than that - and to be honest might still be slightly deflationary if you take into account lost wallets.  (After all, it's not the number of wallets lost that matters... it's the number of coins in them).

Add to that the fact that some people will have put their wallets on thumbdrives and deleted the clients for long-term cold storage. While it's possible they will load them to stake at least once per year, it's also quite likely that they did that because they don't feel the coins are safe on any Internet connected machine.

I'm figuring that after the first full year of existence we'll see around 500K coins actually added to the total... and it might be less than that when you consider how many people leave their coins on the exchanges (and MintPal doesn't stake their coins AFAIK).
