Even if that was meaningful, and it isn't, one of them skipped a week in a period when there was quite literally an update a week (and, thanks to 1.07, sometimes one every 36 hours):
1.05 - March 3/launch
1.06 - March 10
1.07/1.08 - March 17/March 18
1.09 - March 25
1.10 - (March 31; didn't happen, oh no missing week)
1.11 - April 7
1.15 was then the first update not to appear a week after the previous one, taking an entire month after 1.13 - which of course missed out 1.14. Was that a skipped week/fortnight?
Did we get all the content/changes/fixes 1.10 or 1.14 were supposed to deliver in 1.11/1.15? We don't know because we don't know anything about how PD decides its version numbers.
There's little reason to suppose that 1.28 was planned, had stuff in it, and then didn't arrive for some reason - particularly as it came and went very neatly a month after Yamauchi said updates have only been monthly because they have and not because they were designed to be, and could be more or less frequent.
People believing wholeheartedly that there's 3-5 cars from January/1.28 coming as well as 3-5 cars from February/1.29 are setting themselves up for disappointment; it'd be great, but it's a notion fundamentally built on nothing. Similarly, those people believing 1.29 is VR2 and VR2 only and PS4 support has ended and whatever else has been said are just pointlessly doom-mongering.
All we know is 1.29 will bring PSVR2 support for PS5 players. Anything else is, at this point, is purest speculation.
