I know there have been some concerns among the left/progressives about vote splitting. I strongly suspect Gil Peñalosa is going to have a lot less support this go around, will drop out early, or might not even register at all.
Last September, when Peñalosa became the default anti-Tory candidate, he was able to hire some NDP staffers and get the blessing of some of the party brass. This will not happen this time around. He will have far less resources and money for his second attempt.
Peñalosa has also rubbed some people the wrong way, myself included, by using his email list of supporters and donors from last year to promote urban planning workshops that he sells.
