Current return is now around 40% per year, or 3.3% per month.. 
Dunno -- I just did some samples, and wagered per hour is way, way higher than it has ever been. It's more than 4x the average of the last two weeks. just-dice.com is currently clocking over 1,100 btc wagered per hour. That implies 11 btc an hour, 264 btc a day, or 1,848 a week. Invested is currently 19,447 and change. This implies profits of about 9.5% a week -- almost four times what they were before my announcement.
I'm willing to bet the amount wagered will fluctuate over time, someone should graph it by keeping track of how much is invested and wagered at any particular time. I think I'll start keeping track of this myself because I find it personally interesting.
