Replacement of FM458+EXM438 in S7-1500

Hello Experts

As per the below announcement, FM458 + associated modules have been phased out. :

Announcement of product phase-out for application module FM458-1 DP for SIMATIC S7-400

No replacements have been suggested ( only a general indication to use S7-1500 series )

We have been using FM458 + EXM338 for rolling mill and other similar applications requiring high speed control. 
 
Are there any modules in S7-1500 which can match the features and performance of FM458 & EXM 438. and to which D7 sys programs can be migrated ?

Our local Siemens contact partners are clueless about this. 

Thanks
