RCEs can be used to go onto Track I

The InventiveStep blog gives some useful information on the USPTO's prioritized examination:

Several weeks ago, the PTO announced an expansion of the procedures for prioritized examination. Under the previous rule, Track I prioritized examination could only be requested for new applications or for applications that were re-filed as continuing applications. Now, applicants may file Requests for Continued Examination to obtain Track I status, provided that the appropriate fees are paid and the application is limited to 30 claims and 4 independent claims.
