Couple of things, that number of concurrent players will increase. Why? Because people like me have been wanting to play, and haven't been able to.

Also, there was a number for this game to be successful. A number that with subs would allow them to make a profit and still afford to churn out new content. It would appear that we are past that number, which is a really good sign!

I'm sure after Beta 4, SE started putting in place measures to expand their servers. Such measures are not a quick fix.
