I quite agree, this is really quick turnaround. When 4E came out were quite enthusiastic, but after playing with it for about 3 years we drifted back towards a simpler, fewer options version. With all the powers and abilities that started coming out nobody knew how the rules worked anymore! Now we run a stripped down d20 analog version with horribly mortal characters and it's quite fun.

I'll keep abreast of this 5E, though!
