Hold up, hold up... lemme redo some stats here, cos looking back at my old stats even I'm not entirely sure about some of those numbers. And this would be because there are different ways to count MPs cos counting toys is incredibly subjective blah blah blah, don't wanna bring up a toy counting controversy again but basically I've forgotten how I counted for the old table that I made.

So I've done a recount and I'll explain how it was done too. First, here are all the MPs released by Takara(TOMY) according to all base-number releases★. This means that I'm counting MP1 all the way to MP38, but I am not including non-base numbered releases like MP1B, MP11S, MP12G etc. - just for the sake of simplicity I'm just not counting them for this survey. Sorry, Coneheads. Also, I've counted each cassette character separately, so MP13 counts as 2 (Soundwave & Laserbeak) etc. If you don't agree with me counting the Cassettes separately, then just adjust 2013's count from 9 down to 6.
So anyway, this is what I got...


Now for the benefit of fans like Ralph Wiggum, I then took these MPs and removed all toys that are not original G1 characters. BW MPs gone and all "Neo G1" characters like Exhaust, Road Rage etc. were removed. Again, if you don't want to count the Cassettes separately then 2013's count is 6 not 9. I also excluded variants of the same character & mould, hence why 2006 dropped down to 1 as I discounted MP4.
This is what I got...


Even with these parameters in place we can see that the number of MPs released by TakaraTOMY post-2012 still outnumber those released up to 2011. When we look at all numbered release, the lowest point from 2012-17 is still higher than the highest point in 2004-11, and even if we restrict it to just Original G1 characters, the lowest point in 2015 still matches the peak that pre-2012 MPs hit in 2007 & 2011.

Yeah, quite frankly it really feels like we're being quite spoiled with MPs right now. I don't see how this reflects the line being in any form of decline.

★ How I counted MPs. MPs discounted from in the second count denoted in blue.
2004 = MP1(1)
2005 = MP2(1)
2006 = MP3(1) MP4(1)
2007 = MP5(1) MP6(1)
2008 = MP7(1)
2009 = MP8(1)
2010 = (0)
2011 = MP9(1) MP10(1)
2012 = MP11(1) MP12(1) MP14(1)
2013 = MP13(2) MP15(2) MP16(2) MP17(1) MP18(1) MP19(1)
2014 = MP20(1) MP21(1) MP22(1)
2015 = MP23(1) MP24(1) MP25(1) MP26(1)
2016 = MP27(1) MP28(1) MP29(1) MP30(1) MP31(1) MP32(1) MP33(1)
2017 = MP34(1) MP35(1) MP36(1) MP37(1) MP38(1)

I don't see the harm in TakaraTOMY releasing non-original G1 MPs. G1 fans are still getting a good number of original G1 MPs. Let other TF fans have their fun too. The total number of numbered non-G1 MPs is just 5 out of a total of 38 numbered MP releases. This means that 36/41 or 88% numbered MPs released by TakaraTOMY are G1. Or if you don't want to count the Cassettes separately then it's 33/38 or 87%. The overwhelming majority of MPs are G1 and the number of G1-only MPs being released is still higher than it was when MPs was exclusively G1 [2004-2014]).
