New A600 accellerators

But Vampire uses FPGA, and Lotharek board uses a real 68EC020 processor + FPU, so it might have  a higher level of compatibility?

The 68EC020 is the real thing which defines the standard which compatibility is based on.

Also - does Vampire do '020+882 instructions?  Isn't it just - basically - a very fast 68000?

The Apollo is mostly 68020 and 68000 compatible. Compatibility with the 68000 is much easier than the 68020. The new Vampire board has enough room for at least a partial FPU (similar to the 68060 implementation). I don't know if the current FPU implementation is as complete as the 68060 or is even extended precision like the original. I haven't seen FPU specific software running on the new Vampire so there are probably bugs.

Will the Vampire accelerator have extra fast memory?

64 MB according to http://www.majsta.com/.

And is it available now?

Two more weeks or, rather, read the web site above .

How much RAM will "full HD" RTG on the HDMI require?

I would expect 1920x1080 to use at least 8 MB of memory. Majsta is more concerned with keeping his accelerators for 68000 Amigas affordable. Accelerators for the 1200, 3000(T), 4000(T), CD32 etc. should receive more memory.
