It's obvious that many of the existing Ruby implementations will continue to be adopted, each with their own strengths and weaknesses. It is also my understanding that they intend to adopt a business model in which they'd have a free version (that will suffice for most people's needs) as well, and they plan to make commercial versions affordable. But we don't know what they're going to charge yet, so it's really just speculation at this point. They are going to release the Ruby parts as Open Source and it's not set in stone that they're going to keep the VM closed either. However, if they choose not to make it FOSS, it's very unlikely that MagLev will become the single most popular choice. That said, companies pay a lot of money in hardware and hosting fees, so if the speed claims were to be true, many companies would have no qualms about paying for a much faster implementation. It's not going to be everyone's cup of tea, but it's a choice, and choices are usually good.
