Yes, there is to early adopters, and that is block reward halving much quicker.
Broseph, try to stay relevant. Block speed has nothing to do with block reward, and litecoin is designed to halve the reward at the same ~4yr pace as bitcoin.
Litecoin's reward halves at 200k blocks.
edit: Okay, maybe if Cosbycoin's confirmed it that isn't true. I had thought coblee didn't change it, but I must be mistaken.
