Looks like we'll likely get a plastic White Raven in the upcoming Kickstarter (or Black Python, if you prefer).
It's just so hard to swallow the high BV of the newer tech! 2900 for the White Raven at 75 tonnes. That being said, the Ravens never really had faction-specific 'Mechs until they moved to the Inner Sphere and became relevant to the plot. Instead of the usual raft of Timber Wolves, Novas, and Warhawks, I really want to field a Star that is absolutely, clearly a Snow Raven Star - including our faction-specific technology in the Ferro-Lamellor, too!
I would love to see the War Crow and Carrion Crow appear in plastic, since they were in the Rec Guides. Plus, a Deimos would be lovely...
