Toshiba Will Not Release New 15K RPM HDDs
It seems that production of the fastest 15k rpm HDDs are on the decline, Toshiba sees no reason to release news HDDs with that rotational. In a news-item website Golem reports about this news, there is not enough demand for fast HDDs due to to the rising demand of SSDs.
Toshiba currently has six 15k rpm models listed in various pricewatch engines, the largest capacity one is a 600GB model. Larger capacities would have certainly be possible, but Toshiba doesn't see any demand in that as at that performance and volume level the demand for SSDs simply is bigger. Also the price per GB compared to an SSD does not make much sense anymore they state, as such the 15K rpm hard drives are too expensive compared to the significantly faster SSDs.
HDDs aren't dinosaurs just yet though. It seems it all remains to be different for 10K rpm HDDs, Toshiba will release a new series based on that speed. Currently the maximum capacity for 10K RPM HDDs is 1.8TB. The demand for 7200 rpm HDDs will remain strong they claim, low-perf 7200 rpm HDDs are still in high demand even in the server segment as there is a NAND shortage.
Toshiba does mention that a full migration from HDD to NAND storage simply is not an option short term. The storage demand is too high as production capacities are not enough to keep up with the current hard disk business and thus demand. This is one of the reasons why you will have noticed that SSDs have become roughly 20% more expensive compared to half a year ago. There is a NAND storage shortage.

I understand why they existed before SSD's become price reachable.
Now there's no point, anyone wanting performance will get an SSD and for storage an HDD.

Makes sense. Faster HDDs are more power hungry, noisy, hot, expensive, and failure-prone than their slower counterparts. Meanwhile, you could buy an SSD for a similar price and get something more efficient, quieter, cooler, smaller, and reliable than the slower HDDs. Seems like a no-brainer.
Nowadays, you buy an HDD when you just need oodles of terabytes for a low price. Most things that need so much space don't care much about seek times. With RAID1, sequential read times are pretty fast on high-capacity drives.

Enterprise machines running RAID1 - does that even exist?

Why wouldn't they? RAID1 is mirroring - redundancy is crucial in servers.
Are you sure you're not confusing RAID0 or JBOD? Because those are pretty stupid to use in servers.

I am almost not surprised, 15k drives are not cheap and with SSD reliability on the rise well....The choice is simple.
