This post is purely speculative:
There is some work going on in the plot marked in red on this image, a fair bit behind Euro-Mir.
This could just be more expansion to the admistration, but might also be a replacement for the buildings closer to the coaster.
Directly adjacent to it, are two narrow buildings which house e.g. the first aid. Those could be moved elsewhere, expcet for first aid none of them has to be as close to the park. Next to them are 2 more buildings which
could also be removed to make room for quite a expansion to the area.
If the park were to utilise that space for the new ride, it would likely safe our beloved Bench (which still needs some brighter LEDs in the last scene, I regained vision after 30 seconds, that is way too short!).
However, what makes me doubt this, is the weird obsession of the Park to slap new administrative buildings into the park itself, instead of areas outside of it. Additionaly, when I last saw the construction site, it was just beginning to form, so they could build anything beween a new bike rack and a skyscraper.
To make matters worse, it was said that the Russian area would be shrunken, implying that either some buildings or bench need to go.
But this might also be related to the Euro-Mir replacement not having a russian theme (French Guyana maybe? That's were the ESA does their rocket launches), which by itself removes a bit of the Russian area.
Euro-Mir itself is about 3,000m², adding the adjascent buildings brings that number up to 4,000m². If some or all of the buildings next to it were to be demolished, the total area could be brought up to a 9,000m². For comparison: Klugheim (minus the large cattle pen) is about 7,000m².
So, there a some opportunities for the park, but it all depends how much they are willing to demolish/relocate. They might just build the new Coaster Tiki Waka style above and next to the existing area, maybe even sacrifice bench in the process.
Personally, I'd love to see that section expanded, this is the only space left in the park that's not used for Traumatica.
