Gonna ignore Dynamaxing til we know all of the mechanics in detail and it's implemented correctly.
I think Orbeetle may actually have a solid defensive niche. Yes, Bug/Psychic has a lot of bad weaknesses, but a 4x resist to Fighting and 2x resistance to Grass, Psychic, and Ground, are all very useful. Plus, 60/110/120 defense aren't shabby especially with Recover, base 90 Speed, the BOOTIES, and Body Press, which lets Orbeetle 2HKO Tyranitar and Bisharp while outspeeding them (and you live Sucker Punch handily). Interestingly, Orbeetle could have walled Mega Medicham, which can only beat it with Thunder Punch in Electric Terrain (and even then, a max Defensive Orbeetle set wins). Orbeetle also has access to U-Turn, meaning it isn't a total momentum sapper either.
Actually, Body Press is a big damn deal (IMO). Notably, Cofagrigus (and it's Galorian variant) and Bronzong (and Avalugg and some other notable mons) get it, letting them do serious damage (OHKO/2HKO, depending on how the mechanic works) to Tyranitar and Bisharp (and Excadrill), which earlier were huge threats that could switch in and Pursuit trap or threaten to set up.
