I don't get an excitement. There is already IDA Pro and Binary Ninja, developing at a big pace and with actual support. Moreover, there is FOSS radare2[1] and Cutter[2], that also being developed at crazy speed. We have even work in progress decompiler radeco[3][4], though there is still a lot to be done. If people would contribute - there is a lot of time until March (time of GHIDRA release).
