Coin Shop Question

I'm curious if there is any information publicly available that specifies what will be available on the shop in 2wks? The reason is of course one for the raiding guilds out there and for players who plan to donate for gear. I won't take gear from my guildies in <Rage> because I plan to donate for pre-T5 BIS. But if some of the T4 or offset pieces will not be available I should be trying to get those now.

To what extent has this been discussed publicly so far? I am aware that it was said only items dropped from bosses on farm would be available, but it seems to be more intuitive programmatically to simply include everything that is not available in T5 when the market opens, if only to help the server pay for R&D and continued service, which I am happy to oblige if there is something of value available.
