You mean it's bad that they're not trying to whip up a frenzy by announcing the date well in advance, thus encouraging people to pre-order without details of the expansion? Sometimes, you surprise me, Gilrond
I don't think pre-ordering is a good practice. Why would you pay for something in advance before you even can use it, unless we are talking about crowdfunding / investment? But communicating plans and roadmaps is good. It helps others plan things. Not sure why it's supposed to cause frenzy.
