So tonight I grabbed the white theme booster (because I like them) and besides the 5 copies of the common white non-basic land, all the cards were the regular frame.
Is this a known thing that the theme boosters are only regular frame? I thought maybe since the draft boosters had a chance of showcase frames, the theme boosters might also.
Has this been discussed?
It is not said directly, but the article lists all special frames draft boosters and collector boosters can have, and nothing about them is said when talking about theme boosters, implying it only gets regular frame cards.
Borderless Planeswalkers are not the same thing as Extended Art cards. Extended Art have the same art as the regular card, just cropped differently to fit a larger box, and still have a border on most the card; Borderless planeswalkers have an alternate art and no border at all.
It is known, from the original article about the new frames and boosters: https://magic.wizards.com/en/articles/archive/making-magic/project-booster-fun-2019-07-20

See: borderless vs regular Oko; extended vs regular Torbran
Extended Art are exclusive to the collector boosters, but Borderless can be found on regular boosters too.
