There's good chance that we don't even see the N9 yet in Nokia World so i doubt we see MeeGo tablet either.
There's no recent rumours about any Nokia tablet either. Plus Nokia exec said that they don't have plans for MeeGo tablet. Granted that might not mean that we wouldn't still see MeeGo tablet this year from Nokia.
If anything i would like to see Nokia MeeGo tablet more than N9.
