This thing had all but dropped off my radar screen.  An enlarged hull?  That will require more than a modest upgrade won't it?  At the very least it will require testing of all functions of the vehicle, from weapons carriage, to flotation, to blast protection, direct fire protection, etc...

Are they buying time or is this really a desired capability?  I ask because troop comfort hasn't exactly been a requirement in other vehicles they've built so far.
