Please keep in mind that warrants can be repriced and/or extended. Maybe that's why not a lot of people are pouring money into it on the notion it will be at least $1 before expiry. Just throwing this into the mix as it seems like most people here are already convinced these are not a possibility.

Disclosure: I have both TFSA accounts maxed out and hold PTK exclusively with a little cash on a GTC order. We're on the same team. :)
