There will be ONE MeeGo from Nokia in 2011.
Nokia will release a MeeGo producto this year. It will be the one and only MeeGo from Nokia. It is possible it'll be a phone, may be a N950. Even it is possible that it can't carry MeeGo name because of some differences (it is a mix of Maemo 6 and MeeGo).
The only way we see more MeeGo from Nokia in the future is that Nokia crhas with Windows Phone 7 phones, and that Micrsoft doesn't buy that. But is very difficiult that those both situation be produced.
