I hate to always keep saying it, but we don't know. =S

Sylestia's in a very rapid change (well, depending on how you view it haha) state atm so I really have no idea if they will or won't.

They do have a sale price though, unlike the Ingredients. So you can just vendor leftover ones if they become un-used.

I'd rather be able to keep them and use them next year, lol... but good to know, thanks.

And yes, that's a hint that it's my vote to make this a part of the yearly event. I'm sure it won't take long for folks to breed what is available into a four viz Windchaser, but I'd still like a chance to get my own tagged. My luck is running pretty cold this fest though, so I'm betting on next year. I doubt I'll even come close to the 1000 valentines needed to buy an egg *sigh*, and I used what diamonds I had on new stables. So, I'll be ship out of luck on these, I guess.
