It appears as if the wave of Hasbro exclusives that Walgreens will be carrying will be available online, and maybe NOT in stores. All 3 of the Hasbro Exclusives now have listings on Walgreens.com:
Prototype Boba Fett
There is no timeframe for the release, however Hasbro has made it clear that more information on these will be made available at SDCC this week.
