From what I’ve seen there’s already an intense trend for converting Ikea furnature into these sorts of tables.
Ikea would have to be dense to have not noticed it, if I have (I’ve not much interest in these things).
That’s be a bit like smaller makers of fine quality furniture and cabinetry going out of business. Ikea hasn’t killed them, or much impacted their market from what I can tell. The sort of person looking for furniture at a max of a few hundred dollars an item. Is not the sort of person shopping the smaller and custom gaming tables from small builders. Prices I’ve seen are in the $1000+ range, or close enough to not matter.
Ikea operates in a different market than smaller or higher end furniture producers. What Ikea is going to knock out of the market is DIY options, kits and the like.
