Which Star Wars Titanium ships do you see as being "sleepers-" that is, they are being passed up (for the most part) now but will be popular in the long run?
My #1 choice is the Speeder Bike with the Biker Scout. Why? With Luke on Speeder Bike and Leia on Speeder Bike announced at Toy Fair 2006, if you want to display these opened you gotta' give Luke and Leia something to chase after or be chased by- and if Hasbro does not re-release the Speeder Bike with Biker Scout then there won't be any anywhere by the time Luke and Leia are released.
With this in mind, I picked up a Biker Scout Speeder Bike last night- so I'll have 2 opened to make a nifty display with someday. I may pick up a 3rd Speeder Bike with Biker Scout if I can find one, too. 'Round here, Titaniums are scarce!
My #2 and #3 choices are the Vulture Droid and Droid Tri-Fighter respectively. With 4 colors of ROTS Jedi Starfighters already released (and the fans pushing/pulling for a 5th Color- the Purple Mace Windu version as seen in the Clone Wars cartoon series), they'll need something to chase when you display them. I'm going to pick up an extra Vulture Droid tonight if there's one still at the only store in town where Titaniums are on the shelves for just that reason.
These are my Top 3 "Sleeper" ships- ones that will probably be harder to get as time goes on even though they are/were relatively plentiful at retail.
Otherwise, I think the 5-Pack repaints will also be popular in the years to come, as well as the Star Destroyers and Republic Assault Cruisers. These are all different beasts, however- and it appears that 5-Pack number 4 will have a Star Destroyer in it for all those who missed them in Wal-Mart's Wave 2 last year.
Speaking of which-
Everyone who's catching up on Titaniums that does not have the 5-Pack number 2 with the "Raw Metal" TIE Bomber should go to Wal-Mart.com and order one, NOW. Go there and search for "Star Wars Die-Cast" and you'll find them for $19.99. Good luck there! They are probably close to selling out...
SO! What are your "Sleeper" ships? Why?
