Yo artpunk,
We did not test it on iPad yet, but as long as iOS responds to standard MIDI messages, I suppose it should just run fine.
On the second question, I will not give any hint on our current works / future releases. But of course this iPad intrigues us as well... 
Thank you for your quick reply Antoine. I did some research on the iPad midi-controllers compatibility issues and found some good news, at least as far as the Factory keyboard is concerned; according to the link below at iosmidi.com, the Factory keyboard works (although probably will need to be externally powered):

re: your answer to question 2 - of course, I quite understand! If Arturia's intrigue ever leads you to need an enthusiastic beta tester at any future stage, please feel free to contact me!! 
I feel I will be purchasing the Factory very soon!
I've tried connected directly to the iPad 2 Camera Connect Kit and it's underpowered (unfortunately) so the iPad refuses to recognize it.
Then, I tried it while connected to mains and (surprisingly) the iPad 2 still complains about the controller drawing too much power, so it refuses to accept it.
The only way to connect THE FACTORY controller to an iPad through the Camera Kit is by using a powered USB HUB. As soon as I had that between those two, I was able to control and CoreMIDI aware iPad app with THE FACTORY controller.
One interesting note though... after that connection is established through the powered USB HUB, I can unplug that HUB from the mains and it still works!
Which is a curious fact. Maybe the iPad only samples/checks the power drainage at the connection event OR the controller causes a power spike at connection time and then keeps going on a lower consumption level than initially.
As a side note and maybe feature suggestion, I wished the smaller Arturia controllers were lighter both on weight and power usage.
