I was wondering if when the new achievement changes come in, will the achievements we currently have be "reset"?

The reason I'm asking this, is there will come a point where some achievements will no longer be able to attained because of the changes coming in 2.10 and therefore make it impossible for some of the more hardcore achievement hunters (to join when the ps3 version launches) to gain every achievement. I'd really like to know how this will be handled, for example will the achievements we currently have for things like guildtoken purchases be transfered to the equivalent achievement when guildtokens are abolished?

Thanks in advance.
