[SOLVED] DDJ Wego2

Hey guys, I'm really excited about the DDJ Wego2 but had a few questions:

1) Can you record a set on djay2?

2) Can I use a 64GB ipad 4?

3) When is the exact release date?

4) Is there a bag / deck saver for it?

5) Does it come with the battery pack or is it optional? If so, how much does it cost?

Thanks!
