Neither of these characters had any "flavor" feats which a fighter can usually afford to spend at least 1 feat on (since they get so many).
Neither fighter took Improved Initiative or Leadership, 2 common feats for fighters.
Neither of these characters had any feats for ranged attacks, mounted combat, or shield attacks, and both builds assumed no exotic weapons.
In my estimation, both seem to have a long while farther (compared to 3.0) to go before a fighter "prestige(s) it".
Compare the fighter to the cleric or sorceror, who at present have very little reason to stay as clerics and sorcerors (turning+familiar), and I'd say there isnt much of a problem. Wizards are right behind with them missing out on slightly more, bonus feats and familiar progression.
As for metamagic, well they didn't totally redo the system, but they did tweak it. I'd say the system works OK as is, and adding another metamagic feat (to an already healthy list) can only be seen as a good thing. Hopefully the slot modifier for widen was considered for lowering.
