4580 blocks until the end of limit phase (about 6 days)
Actually the block reward should go to 8 tomorrow already if the specs are correct as there should be a vote limit of 8 for the last 3600 blocks of limit phase, and that will happen in ~850 blocks.
Block reward change was at block 129'600, next reward change is at block 133'200 when I expect 8 coins/block to kick in. I wrote about small wallet bug before, about block reward change error - in wallet change is about 700 blocks later than it actual is on network.
