MAC Antonio Lopez...to buy or not....?

I've spent way too much at MAC lately!  But now they have this gorgeous collection coming out (and not below is the beautiful coral face palette).  How much makeup do I need?  How much can I write about and when to just let it go and enjoy what I have?  Limited edition makes it more tempting....my favorite pieces below ...excluding the coral face palette and nude lip one...too many pictures is too many.

What will I buy given that I just committed to their retro matte lipsticks....?
