RE:Gatekeeper takeover candidates I'm rather with you on these possible suitors. There are a LOT of unknowns, however and it all depends on the quality and market penetration Siemans achieves with this product.
If it's good, major competitors may want to snatch a competitive product. Good premium in that scenario.
If it's good and they dominate but little GSI is demonstrably better, they may want to absorb GSI technology themselves.
If they're better ... the defensive tone of comments here suggests we are a bit shaken by this revelation. Need to keep faith in the respect shown for our products elsewhere.
