No. Programming languages need two things to become mainstream. First they need a very extensive library of support such as windowing, network, and about 50 other topics. Second they need a compelling reason to use the language itself. The compelling reason could be that the language is so nifty or elegant that it is worth the effort. In procedural languages it is hard to imagine anything better than what we have. In non-procedural languages there may be some new ideas yet to be thought of. Another compelling reason for a new language is marketing suits. Some company has a very cool new product and in order to lock you in they invent a new language to program it. Laaaaaaaaame. Only Microsoft would be stupid enough to try that again (C# was a case in point where they still had the muscle to pull it off.) Google could do it for a special search language but are not that silly.
