There are a few improvements that could still be useful:
i) FPGA on a newer process so it can clock higher. For faster 68k in the Amiga core and pentium 1 equivalent speeds in the x86 core.
ii) Faster ARM chip and better ARM-FPGA fabric, opening up hybrid emulation. Currently the ARM-FPGA layer is a real bottleneck and also the ARM core is a little slow.
iii) More spare IO to allow per-system custom io boards.
iv) Built in IO/memory board so they can fit in a nicely designed case rather than the current eyesore.

I'd hope for replacement with the open standard RISC-V instead, as used in many of the newer FPGA families.
