I am probably in the minority here, but I will miss the 5POA line if/when it is replaced by 5" GOA. I had pretty much shored up my collection by 2008, and the first run of Vintage did not entice me much, except for the random "new" figure (and that was when they could be found at all...) The new Vintage doesn't do much for me either...I have bought 2 so far (Hoth Rebel and a Mimban Stormie.) Those 80s GIJoe-style leg and hip joints are just plain ugly to me and don't fit in my collection. I will get Crait Luke when/if I see it, but I'm not looking out for much of anything else so far announced.
I have enjoyed collecting Disney-era 5POA figures in a limited capacity, and I don't think I will continue if they jump scales, just as i never got into the 6" line. I suppose the only TRoS figures I can wind up with is the couple of Vintage figures they will put out. Kind of a dud way to end the saga.
