Yes, don't despair...often developers will save and release entire floors (sometimes better floors and views) at a later date to the general public. If you really do want to buy pre-construction and be one of the first to buy, it's best to get a good real estate agent (which is free for you anyway since the developer pays the agent commissions and not you!). That way you can be a "VIP". It doesn't mean that you have to be Donald Trump lol. Most VIP's are hard-working investors...without them very little of what is built now would get built as end-users often don't want to put down a 20% downpayment and wait 4 years until occupancy...so they prefer to buy resale and see what they are buying vs. investors who can visualize the unit and view from plans.
That said, some of the best incentives for new projects are in ones that have been on the market for a bit but still haven't got their financing in place to start construction.
Good luck. Yonge & Rich is a great project and a great investment. This neighbourhood bordering the financial district needs more residential buildings and people living here so that there is some more vibrancy in the area on weekends!
