The crash videos seem to be consistent with a lighting pattern indicating gear down. This may not have been a regular go around, but windshear escape, the altitude from which it started being consistent with system parameters. It could be possible to forget the gear however (been there, done that), especially IF fatigue is a factor, but I wouldn't expect to see that level of performance with gear down at standard GA thrust.
As for Colgan, that was a crash where the captain had repeatedly failed check rides and so therefore has to have been of suspect ability, and a relatively inexperienced FO, both of whom managed to grossly mishandle the situation. That flight crew profile does not appear to match this incident, but that does not mean any human is immune from making mistakes.
