You will get no argument from me that talent has everything to do with how fast a players moves up through the minor leagues. But; with that said, the Astros former regime had a bad habit of moving too slowly. Case in point; Hunter Pence was at AA when they moved him to the majors. So, does that mean he wasn't good enough to be in AAA??? That is beyond explanation.
Now that there is some talent coming into the minors; I would hope the the new leadership in the Astros front office implements the "Peter Principle". You rise to the level of your incompetence. It's time to move players up when they're ready; not a year or so later. One quick example and I'm sure there are several others that would be better; but, Tanner Bushue (quite possibly a very poor choice). If there is any future hope for this 20 year old; he needs to be in Corpus Christie no later than mid season 2012. There is little way to improve in baseball while competing with lesser or equal talent to yourself.
Without the organization challenging these young players (dare I say pushing players to improve or cease to be players); saying the Astros should be a legitimate playoff contender in 2015 may be a pipe dream.
