It has always been up to the EMs if they would like to announce that Mesanna is coming, some EMs did it, some made it in a riddle and some decided not to tell at all.
When I played I said to the EMs they didnt need to announce it, because they dont like xsharders being there just for the items.
Even tho I don't play anymore I logged into ICQ and I see I had a 1½ hours heads up that mesanna was going to be coming to Europa at that evening.
So I guess some people knew, but its hard to keep those things secret in an MMO.
But if collectors want the items they can always pay the prices, its always been like that. on Europa they can always buy the items cheaper than what they pay on other shads because 100m on ATL doesnt have some value as 100m on Europa.
But gold is and will continue to be useless, Rare items will always be better to have than gold. So if anyone decides to sell, sell for high price, try rares board or demand a lot more for buyers. Some people know that in the past I bought for cheap and sold for a lot more and some people that knew that asked for more and I paid more than I normally would. Its all about knowing what items are worth or will be worth within a few weeks.
