According to 148apps.biz there are 823 apps being submitted to the app store every day for the month of February. If it’s maintained this will be a new record, beating the 821 apps per day for last December.
This rate implies 300k apps per year run rate. Of course, the submission rate has been increasing steadily so it might not be long before we see 1000 apps per day.
