So I checked
Champions #1 on the PREVIEWS World site and yeah its listed as "Champions #1", no "(of 5)" added on at the end or anything like that. Checked to make sure the code, FEB200806, is the same as the solicit they showed last month that listed the series as a mini and yeah its the correct one all right.
Issue #2 also has no "(of 5)" at the end same as this month's solicit.
Either the whole "(of 5)" thing was a typo and the series was always on track to be an ongoing.
Or enough people complained about it online for them to change the mini back into a ongoing.
Either way I am now
cautiously optimistic that the series will live past 5 issues now. But only time, and the next few solicits, will tell.
