It seems Wind became semi-organised with their tariff changes over the past few weeks. I was on the Mega-15000 since it was introduced last year and until about 2.5 weeks ago I was still being charged at the OLD rate but suddenly it swapped over to the super expensive EUR 0.9/kb rate around the 2nd week in February. I found this odd as they did tell us all by SMS the price was changing in December but hey, I guess Wind are "organised" and needed 2 months to implement it
Anyway, I'd assume that this new rate of 0.9/kb will now apply to all their data pack offers so in my opinion the only one that is semi-interesting is Mega-15000 which gives a reasonable amount of data for an OK price when roaming. At this price of 30 Euro per month I know of nothing in Belgium (where I spend most of my time) that can compete.
