Kind of,LCA mark 2 is 4 year old program.
the speed at which HAL and ADA are progressing is commendable.
main difference is the eco system which is running tech development in parallel.
Actually MK1a did not came out of nowhere, original MK2 whose work started in 2009 became MK1a without F414.
New MK2 with canards work started after 2014 only.
Now First flight of MK2 is in 2023, while MK1a is 2022.
MK1a is actually quite a mature design , so very quick production is expected.
Basically, you can say MK1a is actually original MK2.
New MK2 is actually MK3, a completely new design.
BTW all MK1 will be changed to MK1a level too.
All in all - IAF would be operating around 250-300 Desi Tejas variants.
It will be the backbone of IAF (our own F16). Be happy about it.
