After 2011, the situation becomes more like fantasy leagues. We could never have a "minor league" system before, since we always knew what guys were going to do "some day." After 2011, it's just an added wrinkle, to speculate about Bryce Harper, for instance.
I'm fine with it, and also fine with keeping things as they always have been (i.e., wait a year for the 2012 set to come out, and the do a 10-round draft based on the actual cards that come out).
Unleashed is another thing that should be put to a vote. I think it's a fine idea if we develop prospects, since some of the prospects have a better chance of showing up in that set.
