^I would wager the 94 stays on Innes to serve the retail along that corridor, but I wouldn't be surprised to see a new express or peak route using the new bypass.
Regarding the timing of the Cumberland Transitway's construction, the TMP update (
http://ottawa.ca/city_hall/master_plans/tmp/tmp_en.pdf), defines two construction phases: Blair to Navan Rd in Phase 1, Increment 1 (roughly sometime before 2017), and Navan to Millenium in Phase 1, Increment 3 (roughly 2021-2025). That said, political priorities can and will change, and this thing could be built whenever.
