It might be a 11-week high, but we have been in this range ($630-$640) for quite a while now.
Nothing has fundamentally changed. I guess we have to break $650 now for some directional indication.
We were at $660-$650 before the Bitfinex hack, then there was a dump down to $600, then Bitfinex was hacked and there was a heavy crash below $600. Getting back above $600 was directional indication enough for me. That's above the price immediately before the Bitfinex hack. Going above $650 will confirm the direction, not give an indication of it.
