It's debatable whether a casino is a good thing, but going with the flow if they have them in other provinces/cities, you can say that it's ok here too. There has been opposition in other places though; in Vancouver opposition last year seems to have put an end to plans for a major casino project right downtown.

^ All the photos looking good, thanks Signal.
I noticed the west side of the TD Place penthouse has dark metal siding so they will probably leave it that way, and the other 3 sides can be done from the rooftop without a crane.
Re: The Battery, whether there is a casino or not, the sale probably means new plans for the hotel, whether they tear it down or just change it, there should be something new to look forward to. Since no new hotels have actually been built downtown recently, a hotel probably with other uses is a good bet for a new development. It would be a shame to lose 127 hotel rooms downtown, only to have them go to Kenmount Road.
