Reply to Traktor Scratch Pro 2 S4 Upgrade Options

So ive been looking at how to upgrade to scratch on the s4 when T2 comes out and seems like there is only one way to do this. You either pre order off NI or Order on April 1st but within those options i have questions. Does anyone know if you preorder Scratch it will arrive on April 1st, like are they shipping a couple days before april 1st so you will receive it then or does it ship that day and depend on your shipping option. Also on april 1st will it be available in stores? Could i walk into Guitar Center or Best Buy on that day and find it on the shelf and buy it there. I love my S4 but cant wait to combine it with vinyl so im trying to get this as soon as possible. Final, is the price $139 for sure or is that just the MSRP off NI. If you have any info to these curiosities please let me know thanks!
