Obviously, the services Roger and Bitmain are involved in won't be allowed to upgrade, but that's their loss at the end of the day.
Roger's own words are; if there are two services doing the exact same thing, but one is cheaper to use, people will use the cheaper service. I usually don't agree with Roger Ver, but he's definitely right on that one.
The TPS is quicker but still not good enough for mass adoption. Eos and cardano are waiting in the background to show bitcoin what tps is supposed to be
Lightning has basically no TPS limit. The more nodes and funded channels there are, the more transaction throughput there is. Ultimately, there is no reason why a globally utilized Lightning Network can't do 100,000TPS. If we look a bit further, there are only a few days (usually the holidays) in a year you actually need insanely high TPS, where the rest of the year 10% of that peak capacity is more than enough to serve day to day usage.
