When will be added new cards to sub the ones recently HOFed, anyone knows? I am currently hoarding classic packs for this reason.

I seem to recall it being mentioned not too long ago as being close to implementation. 

 There also was a mention of replacements being released for the Witchwood set after genn / baku, and the odd / even cards got HOFd.

what are you guys talking about? 

They said in an AMA that they'll replace those cards before the next expansion, so pretty close

Substitute cards such as Icicle have been already added in the game. If you are waiting for cards, that will replace previously HoF ones like Doomguard, Divine Favor etc, then you have to wait a lot until this happens, because there are no news about new cards being implemented (for now).

 Yes, I was waiting for subs for Doomguard and Divine Favor. 

Since I got all rares from classic packs I thought that it was best to wait when they will introduce a new warlock rare and a new pally rare. Being F2P since the very start of Heartstone means to be careful even to these little details, cuz every gold/dust counts :) 

They said they're just looking for the right patch to implement them in, but that it will also take place before the next expansion.

My guess is that they will either come at the time when Arena will reset to a new format (2 months after the RoS release), or a bit later. If the cards are interesting / any good, chances are they might delay the release to about a month before the next expansion to spread out the content and give people that one last month to experiment and have something fresh to play with.

don't get excited those cards are gonna be pack fillers.

 That is very probable; anyway, even a pack filler beats a duplicate :)

I'll be interested to see if they do replace the WW hall of famed cards, as by the time they were to replace them, the set will only be in stndard for 9 months or so. Wild is obviously a different story, so we will see. Would be a shame to see an imbalance in class cards available as we are currently down some for druid, shaman and priest.
