You said it.
Solid state lighting (LEDs) is an absolutely exploding business sector. An LED 2 years ago is like comparing a Playstation 3 from today to an N64 or a comparison similar to that.
LED manufacturers have continuously been bumping the efficacy (lumens/watt) of LEDs while fixture/bulb manufacturers have become better at maximizing their performance (better optical efficiency, thermal efficiency, etc.)
The problem with many of the former LED replacement bulbs is exactly what has been discussed here. They claimed to be a 60W equivalent, when in reality they were only something like a 40W equivalent. This gave the initial impression in the market place that LED bulbs just weren't that good, when the fact was it was just a little before their time.
My recommendation is to wait and judge for yourself if the bulb suits your needs, and don't make a decision about LED replacements based off of one bulb. Every brand is different and uses different LEDs, and some are much better than others.
As for reliability, again early systems ingrained a bad taste in consumers mouthes. A well designed (see: thermally managed) LED bulb can last for 50,000+ hours, I'll let you do the math to determine how long it would last in your application of choice. The length of time it lasts is almost always directly related to how well it is thermally managed; this is why they do not recommend putting them into enclosed fixtures.
I'm excited to see what these bulbs look like in person, I have high hopes.
