Honestly folks - think about it...

• The block reward stays pretty much consistent through the life of the coin.
• The coin now has life past 2 months.
• It preserves a reason to mine it with little diminishing return for miners.

Sure, you lose the "rarity" of the coin now that its mineable for 10 years instead of 2 months, but let's face it - if nobody is mining it, then nobody will be on the network to make the transactions work and the coin will be dead anyway.  This is a PLUS.
