I don't think we've played with it enough to come to that conclusion. While I think you're right that the system requires concentrating on three stats, I don't think you can discount the cost of having your other (non-primarly-stat-based) defenses be low. And, there's currently many feats with off-stat prereqs and I'm sure there will be more. Concentrating on boosting just one stat, or even just two stats, clearly has a meaningful price.
Sorry, I wasn't clear.
A 4e character needs 3 stats, period. His attack stat, a secondary stat (which may or may not be a class stat, depending on how screwy his class is. Clerics, for example, shouldn't take charisma, because it doesn't help them enough). and a tertiary stat. All of these should contribute to one of his defenses. Everything else can be subbed through a feat or two.
Out of these things, the attack stat is the only thing that always matters (and for classes with two attack stats, you pretty much have to dump one... trying to maintain two is far too costly, and since you only ever have 10 attack powers, and you only get the last 2 from your paragon path, definitely not worthwhile).
Con, for the record, isn't worth putting points in if you have to take strength. Investing less than 9 points in CON is strictly inferior to the feats durable and toughness. And the opportunity cost of feats is really, really low, since most of them are garbage. Frankly, between their low effectiveness and how many you can take, the situation is the opposite of what it was in 3e- I'm actively looking for one or two even vaguely useful to plug into a character after I've chosen the handful I actually want.
Similarly, if you care about your other skills at all, Jack of all trades is worth more than putting 5 points in each of your 3 extra, pointless stats. Just make INT your secondary reflex stat, and go to town. If you want to specialize in a skill, skill focus is a lot better than extra stat points.
