Took a long unnecessary way to get to the point... thats how discussions lead to nowhere and misunderstanding when people not read with attention and claim things that are not written. With what I am not pointing at you!
All I was asking, if someone has profound background info about some hints from the last two years, that 055 might feature IEP... nothing less nothing more. I didn't claim that I have any further evidence for that. So for me the question was not irrelevant, but after seeing the result...not worth all that long discussion.
And as I see it now, all explanation why I was asking my first question, was a pure waste of time... Taught me, not to get into such discussions in detail in the future.
According to 052D and 054A yes I regard them as evolutions.
To answer your question (and you have been very patient!), which has probably been indirectly answered in other ways through this long discussion -- the first batch (or first variant) of 055s are not expected to field IEPS, but it is highly expected that 055 will have IEPS in a subsequent batch/variant.
