I agree with Sal about what I think I'd prefer...
I'm not a fan of the Speederbike. Besides the sculpt inaccuracies, the bike itself is too large and has needed an update. A smaller bike would also be a great help since you could adapt it to fit the VTSC Scout so he rides the bike and sits properly with his feet on the pedals and things. Add in the "clear" stand I've been clamoring for now for years, and it'd be such a sweet piece. I'm assuming though, that we'll get repacked, repainted speederbikes... Meh.
The figures though, could make/break my desire to buy the set as well. Like Sal, I'd prefer a mishmashed Hoth Stormtrooper/Snowtrooper, and Biker Scout. The design was used in the Incredible Cross Sections to give the "Hoth Bike" look... It's pretty cool, but would require new tooling I'm afraid. It's doable with some existing parts though... So I'm hoping that's what they go for. I'd dig the figures, maybe try selling the bikes. It's a cool looking design if you see it... I can't find a pic online though.
