As a druid tank I've tanked almost every heroic and 10 & 25 man Naxx with no problems. So I'd say no we aren't becoming obsolete and with the new Savage Defense ability coming soon we'll be even better!!
Savage Defense – this is a new passive ability. When a druid in Dire Bear form deals a melee critical strike, the druid gains a damage shield equal to 25% of their attack power. The next hit completely removes the shield regardless of how much damage was done.
I'm the main tank for my guild and we have cleared every 10 & 25man, and are working on OS+2. I have not had any problem tanking & it could be argued with heroics & LW, a druid is easier to prepair for wolk raiding than most tanks, given the auto- def cap via talents, allowing focus on the survival stats sooner than our plate counter-parts.
stats are a personal choice me i find that the agil stam combo found on most leather to work very well with my druid tank. i have 27k in feral form with 30 something % on dodge and crit. makes tanking pretty easy

I've had hard times healing druid tanks with a lot of hp. They loose health pretty fast and I needed to spam heals to fill it all. I rather see a tank who has invested in avoidance.
There are advantages to prioritizing stamina over avoidance, but I believe that at least in part it is done to impress people. When a non-tank looks at you, he sees your HP. Chances are, that is the only stat that he'll give a second look. I've already seen under-geared tanks allowed to MT because of their high HP value, although the healers could barely keep them up.
I am unsure to what extent that applies to bears though.
