Any power bump you see in Pathfinder is going to feel the biggest at 1st level, and it's going to make less and less difference as the levels advance.
Here's the most obvious and illustrative example:
Take a 1st level character with 10 hit points. Give him 10 more hit points, and you've doubled his power.
Now advance him to 10th level. He has 110 hit points; the extra 10 hit points he got at 1st level is a 10% increase, not a 100% increase.
It will be the same with Pathfinder.
If your PCs are having trouble, you can fix almost any imbalance in the math systems behind the game with two simple fixes:
1) Reduce the hit points of the bad guys by 10-50%.
2) Give the PCs a standing +2 bonus on any d20 roll. Or do it behind the screen, and subtract 2 from enemy ACs and attack rolls.
The Fighter gets extra attack and damage bonus, does he not? Will this not change the math and the balance (both between classes and between characters and monsters)?
Maybe the changes to the magical items can compensate this. If a Fighter has to choose between more strength to gain to-hit and damage or more con to gain survivability, this evens out his "average damage" x "hp" compared to a 3.5 Fighter or a 3PF Barbarian...
(Is this enough?)

My concrete concern with Pathfinder's backwards compatibility are the splat books. Adventures can be tweaked by adding a few extra monsters, this shouldn't be so difficult (assuming averarage to-hits and to-saves are still in the same ballpark).
But I'd hate if I couldn't use the non-PHB core classes anymore, or the Prestige Classes. (I think feats and spells will have less problems). Admittedly, there are only few PrCs I ever bothered to use, but we have used some of the core classes in our group.
We're turning our Savage Tides campaign to Pathfinder, and I already had to say goodbye to my Warlock, which is somewhat sad, because I really enjoyed playing him.
Pathfinders current benefit is that it is a breath of fresh air to anyone involved. You can have played dozens of Fighters in 3.x, but the 3PF Fighter is different and new.
But if Pathfinder will go longer then a year, people will want more. The existing classes won't cut it. And if you have a library of 3.x producs with PrCs and base classes, you want to use them. But do you want to adapt them manually to Pathfinder? (Since Paizo often can't do it, since it's not open content?) Or will I throw those books away and get Paizos equivalent of splatbooks (will there even be any? Would this come at the expense of other products, like adventures?)
Maybe I am worrying to much about this. (Considering I am certainly going 4E, unless I get sorely disappointed, I am from my egoistical perspective). Maybe Paizo already has their ideas how to do this. Maybe the fans have. But I hope this also gets discussed.
