Want to put some money on that?
That toy does nothing better than the M2, its only advantage is lighter weight.
Lighter weight does not a total replacement make.
Saying that thing will replace the M2 is like saying the M249 was going to replace the M60... Instead it simply filled a different role of LMG, while the M60 remaind the GPMG for quite a while, until being replaced by the M240.
