My apologies, you are right, Spell making has not been confirmed to be out.
A more accurate way of putting it is that it's not implemented
yet, and the devs are palying around with various ideas to see whether or not they can make something that works well. Spellmaking's fate is yet undecided.
EDIT: one thing that's certain is that even if it is in, it will be completely different from the spreadsheet-like system we had in Morrowind and Oblivion. They consistently state that the "spreadsheetty feel" of magic is what they disliked the most about it, and that's what they are aiming to ged rid of.
