The new iPads will be announced at the Apple event on Tuesday. Canada usually gets the iPads on the first launch and everything is thinking it should be the same as the years before. It is usually released a week or two after the event. Whether there will be pre-orders or not it's hard to say what the line ups will be like. The first time the iPads were released there were lineups at the Eaton Center, which is where I usually go, even after noon. The following years by the time I got there at noon there were no lineups and no more iPads to buy. So it's hard to say with the new design more like the Mini there might be more people lined up. However if there are Retina Minis then there wont be as much demand for the full size iPad as if there wasn't.
