mythic armor life span?

[ihud]

When the new season comes out and cap increases, will there be new mythic armor and helm?

I'm new this season and am trying to decide what to do with my gold. I don't want to pop 7m on myths, upgrade to hero of legend only to have lvl 41 pinks OP my myths (which I understand cant be sold once upgraded anyway).

I'm thinking it may be better at this stage to save for an arcane pet... even if its HJ as I think it woukd take me a life time to get enough cash for Sam xD.

Thanks for your thoughts in advance.
