I see a lot of AATs and Hyenas (which I've yet to pick up). Swamp Speeder is surprisingly plentiful too.
Only seen Plo Koon's fighter in one store and left it several times, but don't regret it, yet.
Got Xanadu Blood and Droid Gunship via HTS and have yet to see them in a store.
Since I live near Piet it's pretty much the same a bit south from him - I saw Plo Koon's JSF once and that's the one I bought to open. I saw the Xanadu Blood once, I opened it, but it was defective so I returned it.
I recently ordered the Xanadu Blood, Droid Tri-fighter Repaint and the Droid Gunship from HTS - was gonna get them as my openers, but they arrived in mint shape, so they're my MIB ones.
So now, I'm just waiting for the next time the Droid Gunship comes in stock so I can order all four vehicles with the intention of opening the Xanadu Blood, Droid Tri-Fighter and Droid Gunship and keeping the Plo Koon JSF MIB. If by some miracle the Jedi Turbo Speeder comes back in stock, I'll pull the trigger then too.
I have no faith in any of these vehicle waves hitting the stores locally to me, there's just too many of the Hyena Bomber wave ships hanging around - the TRU near where I work got in more ships, but it was a case with the V-19, Hyena Bomber, Trade Federation Tank and Obi-Wan's JSF - just what my area needed, more of the same vehicles that already aren't selling.
