Either way, if this is true, trying to "catch up" to CoD is just... Sad. There is nothing to catch up on if you are already ahead.
A lot of these changes started with Reach but more have been added in Halo 4. Loadouts, perks, things which are kinda like killstreaks, armour abilities etc.
And Halo isn't ahead of COD, COD is far more popular.
