I'm 90% sure that we won't see Wii Fit plus at E3.
Video game companies trademark everything they think about making, or just have the possibility of considering to think about it in the future. If the rumor would be right, and the Wii Fit Plus was in development a month ago, it would mean that they worked on it for months, possibly since the release of Wii Fit, and didn't even bother trademarking it until now.
