I haven’t heard anything official, so don’t take this as fact. This is just my opinion, for whatever it’s worth:
Since Ruby is the last color in the old pricing range, there will probably be one of two things happening this year: a) the price will be raised so that it is the same as the others, b) the line will be discontinued too.
I personally love the Ruby and have recently decided to collect all the Ruby dragons. So, I will be buying them as soon as I can budget them, just to make sure I get them.
