As fas as I've been able to tell, Culdcept will not have integrated twitter functions, but the twitter page will release a amount of cards via their twitter account, so you can see the cards that will be used..
I'm personally quite excited for the update, it'll keep my home menu neater than it is now :3
oh ok I was hoping they do something like ar codes for holidays and special occasions via their twitter account or a instant msg setup so you could connect/chat with other players while you wait for their turn to end or if you want to add someone.
but I suppose this will be fine too.
*edit: I won't be updating to the newest firmware as this doesn't really excite me but If a newer one allows for more than at least I have more to look forward to.
