I have heard the same thing, that it will be a portable solution, but again it's all rumours until it is officially announced.
IF a portable solution happens, it's a cheap and nasty solution, but one that can be rolled out very quickly!
What does have me worried is that the new Sky Interior plane does have the new business class and economy class but no room for IFE in the seat.
Seems very likely to me it's going to be a portable solution
