I don't think it is going to be earth shaking or anything. Sure, parts prices will go up a bit, but that is nothing new. Technical support is continuing, and while it's not at the level it was in Geoff's day, it is still happening.
Bruce probably has more information and perspective than I do, but I don't see it as all that big of a deal. As I said above, I think the combination with Merlin/Metro is probably a positive, given the size of the Metro fleet.
Over time, of course, as the fleet shrinks parts will become more expensive and more difficult to find. That is inevitable, and maybe this is a tiny shove in that direction, but nothing more than that.
