That might be true, if they said there would be "no mechanical changes." That's not what was said.
"Few to no." (Not just "no.")
"Numeric value." (Not "no mechanical changes," but not many changes to stats and abilities.)
That still leaves infinite room for changes to spell-like abilities, supernatural abilities, maneuvers, spells, resistances, immunities, attack forms, and everything that's not specifically a numeric value.
Seems to me that these are still basically templates more or less as we know them.
