"They want to sell the pro and this is one of the incentives to get it."

Yeah , and they are actually being very clever , as a lot of people are looking to dev for the Iphone , and you used to be able to buy Unity Indie and then buy Iphone Basic , which would total in like $600 or something to dev for the Iphone , where as now , if you want to use Unity for Iphone you need Pro plus Iphone kit , which totals now to like $1900. Works out very well for them if you ask me.
