The mind boggles. 
HD650 is my favorite headphone too, just can't help appreciating enough about its sound signature. The thick and warm vocals are just my type, and due to its treble roll off, I never get tired listening to that.
From what I've heard, rumors say that Sennheiser is going to discontinue HD600 instead of HD650 in the OP, and also new series named HD750/HD700 is on the way, could not confirm it though.
I heard that they will stop producing hd600, not hd650
Sennheiser going to release some new stuff? lol
Cool looking forward to your impressions!
A lot of people are talking about a missing product between HD650 and HD800 - maybe? People are talking about HD700 / 750 but I have never seen any official on this.
Also some romurs on 4X9, 5X9 and 6X9.
Their new hits however is on thier wireless phone. There has been lot of praise that its at least up to a wired mid range - but again marketting hive?! I've always been a cable believer - even my mouse is cabled! Those split second delays and "wake ups" from cordless mouse / mice just drives me nuts. I always end up short of USB connections hahaha.
