Hi Igor,
thanks for the kind words.
Phoenix core will be sent to all Vampire 600 users. Problem was in the FPGA I used because it is too small, only 8K LE and that was the only reason why apollo-team had to slowdown to shrink each part of the code. Performance, I have the values but let's keep that as a surprise, let's say that A600 will be your primary Amiga 
You are right - getting the core to 100% work in the small FPGA - was a real challange.
We did spend quite some time on this. :-/
The planned release of the Core is August.
And we so far all looks good that we will be able to launch as planned.
The performance looks very promising - our sniff tests indicate roughly a
performance of 10 times of a 68030 @ 50 MHz system.
