If you consider -playable- wizards to be my "toys", then yes, I feel like it's been taken away. There's no longer any reason to play a fireball-hurling warlock as you'll most likely only dish out 17 points of damage per round (nothing compared to a fighter's 4 attacks, greatsword, Strength bonuses, etc.), and being viewed as nothing more than "useful" by the rest of the party isn't really making any wizard memorable or awe-inspiring. A fighter able to deal 80 points of damage in a round (a fairly easy task), is all that's necessary for a party to win a fight. He might need a spell from the cleric or wizard to ease his task, but that doesn't really make them important.
I believe that you are simply taking the best case scenario for a fighter and comparing it to the worst case scenario for the Wizard.
For example, in your example you claim that a fighter gets 4 attacks which is achievable only by 16th level for a BAB of +16/+11/+6/+1.
Let's compare this to a reasonable Wizard build shall we?
Wizard (Specialty: Enchantment; Barred: Necromancy, Divination)
Level 16
Int 16 (base) + 3 (4 levels) + 6 (enhancement) = 25 (+7)
Relevant Feats: Spell Focus (Enchantment), Greater Spell Focus (Enchantment), Heighten Spell
Relevant DC:
Enchantment (DC 19 + spell level)
Spells per day: 4/6/6/6/5/5/4/4/2 (plus an additional bonus spell of Enchantment each level)
Let's see what our Wizard can do with your hypothetical fighter, shall we?
1. Heightened Dominate Person (DC: 27) -- Hey Fighter, you're my bitch now!
2. Maze (no Save) -- Hey Fighter, why don't you chill out in this maze while I buff up
3. Insanity (DC: 26) -- Hey Fighter, I hope you have a cleric with Heal b/c you are screwed otherwise
4. Contigency (on Wizard) -- If someone tries to swing a melee weapon at me, then Dimension Door me 15 feet backwards.
5. Forcecage (no Save) -- [use Barred version] Hey Fighter, you can sit there for 32 h while I pelt you with evocation spells at my leisure.
I think it is quite clear that, AT THE VERY LEAST, the Wizard and Fighter are balanced. Sure Wizards have been reduced in power with the advent of 3.5, but this was not necessarily a bad thing.
