Its a wise desition indeed to hold up a bit for V5 upgrades.

Remember LM need to release a hotfix related to many issues reported, including DEV, SDK and some other stuff...

Luckly im runing V4.5 yet and didnt upgrade to HF3 neither(seems more like VR update in general) so i dont want to mess with my entire installation again and again and again.

OMG, looking forward for the mighty 767!  8-)
