Two-bladed sword I could live with. Dire flails and double axes looked like they'd take your own head off, dire maces are just quarterstaffs, the urgrosh and gnome hooked hammer seemed silly and I never saw them used, and the bastard sword and dwarven axe were just slight damage upgrades at the cost of a feat. The spiked chain was pretty stupid, to be honest. The idea that there's a weapon out there that's brutally effective but no army in the world ever bothered to use it is just stupid. It's like the idiots who think ninjas can really stop bullets and all that other rubbish - if it was actually possible, the armed forces of various countries would be doing it, and they don't.
I hope we see far more interesting weapons. Personally, I'd love to see weapons used as they actually were in reality - the greatsword is a good example. The "hold the hilt with two hands and use huge sweeping attacks" thing is only one of its uses - and this form of attack was used to break up pike formations. The sword was also used to club, with one hand on the blade and another on the hilt, it was used to stab with a similar grip. So really, the greatsword should be able to deal piercing, bludgeoning and slashing damage, with different levels of damage and reach with each attack, but the 3.5 D&D rules only allow you to use it as a big sweeping weapon, which in a duel-type fight would just get you killed very quickly by someone with a faster weapon.
