I mean, does FFG plan to sell the minis in packs or something like that?

 Not likely, but they are having the promotional Runebound/Descent figures on sale right now for $5 each.

Your best bet is to check on eBay, though the prices might get a little high.

Thanks for answer! 

What figures do you mean? and where can I buy them? 

There were four promotional figures produced for the Realms of Terrinoth event in, what, 2009? 2010? Something like that. Anyway, there were four heroes produced with stat cards for Descent and Runebound, and also Runewars later. They tend to go for exorbitant prices on ebay (I've paid €28 for a Truthseer Kel from a German guy, so German cards but the mini is universal). 

Truthseer Kel

Tobin Farslayer

Jonas the Kind

Nara the Fang

Nara is currently sold out, but the others are still available. Kel tends to be the rarest, incidentally. 

 so there are cards to play with them in runewars and with Descent 2º edition? and I cant get them and the figures for 5 dolars?

And someone knows how much cost the sending?

PD: sorry for my english

Shipping depends on your location. I live in the US and shipping for a figure (I only bought Truthseeker Kel so far, though I intend to buy more if they don't sell out too quickly) is around $4. 

there is international shipping?….xD I am from Spain so…

 ok I saw that I can buy it with 8 dolars of shipping…but in the box I have cards for Runewars and Descent 2º edition? or only 1º edition? and in the picks I dont see runewars cards…

 I think it only comes with the first edition Descent card and the Runebound card. Not sure about Runewars… and the second edition Descent card is only available through the Conversion Kit.

 oh sure! Descent 2 cards are in the kit…but what about Runewars cards?  spalanzani said that they produced runewars cards later so…will I get them if I buy that heroes now?

That said, maybe the 2nd edition of that will fix that too…
