Well, if it's not proven genetic, you can't really call it a new morph.
So generally while oddities are presented, no claims of having the next new morph are made. Things outside genetics (incubation variables for example) can influence a hatchling.
I'm not worried about keeping secrets so as far as genetic combos...
This year I hope to see Lava Diffused & Lava Pewters pipping noses. At least I have my fingers crossed that the pair of hets I have produce them this coming year.
I don't think Lava Charcoals themselves would be too bad of a thing either.
I can't say I know of anyone that's produced those three combos as of yet.
I'm starting a Lava Stripe / Lavamel Stripe project in 2008. I'll have Amels het Lava Stripe to raise up to pair in three years. I think these have already been produced though (though not many exist).
I might have Charcoal & Blizzard Stripes next year depending upon how well my Amel het Charcoal Stripe grows over the next year. I know Charcoal Stripes exist (again, few in number), but I haven't seen anything of Blizzard Stripes yet. Along with this I am raising hets for both Phantom Motley & Phantom Stripe.
Then I think the last two projects that are in progress here are with the Fugly Stripe (suspected Keys Stripe) and a Z Stripe project.
All in all, I'll be raising a lot of hets over the next few years!
