There has been a lot of talk recently about this "max generation" limit. Here are the numbers I think we should be basing our analysis on.

At the moment of writing this:
The last 960 blocks added 500,014 HYP, average of 521 per stake
Last 6720 blocks added 3,397,835 HYP average of 505 per stake
Last 28,800 blocks have added 11,901,493 HYP, average of 413 per stake

The max generation by definition is when each stake will be 1,000 HYP, thus hitting the ceiling each time. Right now we are about halfway to max generation.  I don't think we will hit max generation for a long time, because people will always be trying to size their blocks small enough to get rewards that are less than 1,000. I think what really is going to happen is that there will be a fight to stay under max generation, this will mean smaller blocks, and smaller blocks will mean higher difficulty.

So best thing is to keep an eye on difficulty for now.
