Ok so lyra2z is hashing at 20 Mh/s. A single RX 580 hashes at 3.2 Mh/s. A single Vega64 hashes over 6 Mh/s.
You therefore need 6x RX 580 for one FPGA. But you can get 6x RX 580 probably for around half the price of a single FPGA.

It is as I thought it would be. They are not so terribly powerfull, but they do have a loooot better hash per W ratio. They are expensive, so basically for those with deep pockets. On the other hand as this is still a fairly new field being born again from the ashes, this means there will be some birthing problems etc...In the end I would still bet on GPUs simply because they are proven 100 times over and flexible.

You all have to also bear in mind theat GPUs today are basically 3-4 year old arhitecture. AMD for instance is going on with the same artitecture simply because they did not need to get out anything new. I am sure they (and NVIDIA) have much more powerfull GPUs already prepared but are holding back. So it can as well happen you pay costly for FPGAs just to have both GPU manufacturers release relly powefull cards at the end of the year for instance. And because of mass production they will always be cheaper.

I am definitely going to wait to see how all this plays out

EDIT:

And I just read about 90 days of waranty. Is this correct? I get 90 days of warranty for a 3K$ worth piece of tech. Em ok. Meanwhile I get years of warranty for GPUs. Man if that thing dies after 6 months thats gonna be really bad.

I don't try to put anyone down here don't get me wrong. You seem legit, I am just that voice of doubt in the back of peoples heads

Although I am sure most will ignore me lol.

There are 2 different lyra2zs..

One is 2,8192,256 (zcoin)
The other is 8,8,8 (everything else)

Which one are you talking about? For the 8,8,8 coins the hashrates are significantly lower than 2,8192,256 (zcoin).

limit to cryptonight :
there are 2160BRAM+960URAM in XCVU9P,you can use 38MB in big ram cascade mode,that is 19 core
each cryptonight hash need 1M memory read and write cycles.
if you remove all pipeline,you may get 100H @100MHz per core.
if you all pipeline to improve fmax,you will get slower hashrate.
it maybe very hard to run 100MHz with no pipeline.
assume it is 100MHz,19CORE, the max hashrate is 1900H/s.
if using extern DDR4,the limit is bandwidth,36MB per hash,each DDR4-2400 may get 533H/s,
but the cryptonight random access rate is 16byte ,memory random access rate is 128byte , the valid efficiency is 1/8
each DDR4-2400 may can get 66.6H/s,and 4 DDR4 you get 266H/s

the max theoretical cryptonight hashrate is 1900+266=2166 H/s
Don't dream to get 22KH/s

(No offense meant) You lack an understanding of these devices to be able to say what the theoretical hashrate is. It's clear you've not even read the datasheet.

So the sales has ended or has not started? I see everything is sold out.

Sales have not started

Regarding warranty, we haven't mentioned it and (quite surprisingly) no one has asked about it. The warranty period will be 90 days from the date of delivery.

I think 90 days are not enough to obey EU laws for planned EU:EU sales process.

Indeed Europe has a minimum of 2 years

In that case, we may not ship to EU at all. There's no way we're going to warranty these for that long. Does the EU law take into account devices which will be abused by their owners?
Sent the concern over to the people who are handling these things for us to get their feedback.
Strangely, the devices you (europeans in general) bought from avnet, digikey, etc would also not have a warranty for this time frame (2yrs). So, either avnet / digikey / etc are not compliant with EU law, or there's something else.
