Yes, the iPad 1 went on sale before the iPad 2 was released. The first iPad was launched on April 3, 2010, while the iPad 2 was announced on March 2, 2011, and became available on March 11, 2011. Thus, there was a period during which the original iPad was on the market before the introduction of its successor.
April 3rd...
It is very hard to say when the iPad will go on sale. A good time to check for lower prices is when there is a new model coming out. Often times retailers will discount older products to make room for newer or updated versions.
Of course, Apple has the Ipad for sale, but sometimes you can find them cheaper at retail stores, such as Best Buy. You ask for a 64 GB one, and they will have it.
The First generation iPad is may come down in price when the second generation iPad is released and out for sale. That is expected around March 2011, however, it is also predicted that the iPad will have less memory.
No, you don't have to pre-order the Ipad if you do not want to. You can just wait until they are in stores and go buy one, but if you want to be one of the first persons to get an Ipad delivered to your door the day they are on sale then yes you should pre-order it because i really doubt you can just go to Apple on that day and find out. There will be huge lines that day. Possibly for a few days after the store will be really jam packed with people trying to get their hands on an Ipad before others as well.
March 16th, 2012, though it is available for pre-order at Apple's website as of March 7th, 2012.
You don't have to have an item on sale for any length of time before it can be sold at a sale price. It can go immediately on sale.

Christmas trees normally go on sale during the later part of September and early October. Christmas items are known to go on sale before Halloween and Thanksgiving.
They aren't just going to put IPads on sale you will have to go to a swap meet or any kind of business such as best buy or something when they are having their sales to find one for a cheaper price.
